Hello,

At the moment i'm testing the Mattermost-Server with Mattermail for a Business Partner, but the issue is following:

My Business Partner sends Mails with Roundcube-Webmail with Attachments. This Attachments are insert by Drag&Drop. In the Roundcube-Webmail-App i can see the Attachments in the Mail, but not with an Attachment-Flag. Without this Flag Mattermail don't post the Attachments in Mattermost.

In my Mattermail-Installationpath i have only the 2 Files "config.json" and "mattermail" (App).

Here is my config.json (without real IP-adress and Passwords):
`[
{
"Name": "Mattermost",
"Server": "http://my-ip-adress:8065",
"Team": "makom",
"Channel": "#town-square",
"MattermostUser": "mattermail",
"MattermostPass": "myPassword",
"ImapServer": "my-imap-server.de:993",
"Email": "[email protected]",
"EmailPass": "myPassword",
"MailTemplate": ":incoming_envelope: From: %v\n>%v\n\n%v",
"StartTLS": true,
"Disabled": false,
"Debug": true,
"LinesToPreview": 100,
"NoRedirectChannel": false,
"NoAttachment": false,
"Filter": []

}

]`

It is possible to import the Mails from the Webaccount into Mattermost without the MailTemplate in the config.json, so that Mattermail posts the original Mail with and not a Preview with attachments?

Best regards

Steve Herbst

At the moment if you have a self signed cert on an email server you can't connect through TLS. I set the StartTLS:true in config.json and get this error:

IMAP Emails 17:51:23 TLS handshake failed (x509: cannot validate certificate for x.x.x.x because it doesn't contain any IP SANs)

There is an option in imapClient.StartTLS() to set a config:
https://godoc.org/github.com/mxk/go-imap/imap#Client.StartTLS

The code only sets nil, I think it would work with:
https://godoc.org/crypto/tls#Config

Specifically this option:
InsecureSkipVerify bool

Could I request a config option for this? I will try and see if I can program this myself however Go is new to me.

Thanks.

After getting mattermail to run, im pretty satisfied with it, the only thing I'm missing is a feature to answer Mails and write Mails (like Mailclark for Slack (https://mailclark.ai/help/simple)).

Would it be possible to add this as a feature?

Hi,

I'm currently working on a prototype of Mattermost and Mattermail for our company and I want to use the Mattermail plugin. But when I try to connect to our internal mail server I'm getting the follwing error:

DEBG 12:21:20 Debug mode on

I've already applied the certificate in my local storage and it was added as expected.

On the other hand, I've tried to set the switch 'TLSAcceptAllCerts' to 'true' but I looks like that this does nothing. The whole config looks like (removed personal parts):

"NoRedirectChannel": true,

]
}
]

The Mattermail version that I use is: 3.5.0
The Mattermost version that I use is: 4.2.0

Any help is much appreciated! If you need anything else, please do let me know.
Thank you.

I have Mattermost version 3.4.0. It doesn't show a Channel Handle in the Channel info screen like in the screenshot in Usage step 2 of README.md. It shows a URL in the format http://server/team/channels/lower-kebab-case-channel-name and the channel ID.

I assume that last portion of the url is the Channel Handle. I don't have Mattermail installed yet so I can't confirm. The README should be updated accordingly.

Also, do you support specifying a channel by ID?

It would be very useful to have a feature to send mails to different teams having a similar syntax in the subject as for channels or users. Like: [!team2][#some_channel] My subject
At the moment it needs one mail account for each team. In our use case we have one mail account in the organization to forward mail to Mattermost. But we have different projects using their own teams.

Is there any way of leaving the email unread on the server, or is that the only way mattermail is tracking which emails it's pushed? I'm just testing this out at the moment for a shared inbox, and this is causing a bit of a problem.

Dear authors,

I am trying to set up mattermail to use it together with Mattermost2.2.
Unfortunately, the link to the 2.2 release does not work and I am running into errors while trying to compile the 2.2 version directly. E.g. with Go 1.6.1 I am getting the following error message:
go install

mattermail-2.2

./mattermail.go:248: client.LoginByEmail undefined (type *model.Client has no field or method LoginByEmail)
./mattermail.go:311: client.UploadFile undefined (type *model.Client has no field or method UploadFile, but does have model.uploadFile)

While with go1.2.1to go1.5 I am getting the following error:
package runtime/debug: unrecognized import path "runtime/debug"

I would be glad if you could recommend a go version or upload a release version 2.2.

Thanks in advance

Marco

Hello,
I would like to use MatterMail with Gmail, but Gmail not supporting IMAP.
Is this possible - use MatterMail with Gmail?

Thanks for this plugin.

I have the following problem:
Sometimes we have larger incidents in our ticketssystem that we want to chat about.
Therefore I want to add emails from our ticketsystem to the chatroom that is corresponding with the ticket number.

Our ticketsystem creates emails with the subject tag "[Orgname#0123456789] subject"
Mattermail will forward an email with such an subject neither to the channel #0123456789 nor to "Orgname#0123456789" as it excpects a "[#" in the subject.

I could fork mattermail and remove the "[" from the check. I already saw that at least one forked mattermail for just a similar reason. But then my fork will be not benefit from further updates.

Therefore my request:
Could you make the RegExp a variable that can be editied in the config file?
If I am correct it is just this line in your code:
https://github.com/rodcorsi/mattermail/blob/master/mmail/mattermail.go#L425

Hi,
Some email solutions like Microsoft require you to log in with a Username instead of a full email address.
They are either just or <DOMAIN\username>
Sometimes also the User Principal Name ([email protected]) is possible, but not on every system.
In addition, local domains not always use common TLDs. Instead something like .local .internal is common.

Regards,
Jonas

Hi there,

it would be amazing, if you could get the Mails via POP3, so the Mails will bedeleted from the Relay-Mailbox after Mattermail took them.

Hey,

I wanted to install mattermail in our mattermost envriomnent and test it but run in to several issues. The documentation on how to install mattermail isn't really clear to me.

I downloaded the mattermail-3.0.13.linux.am64.tar.gz into my /opt folder and unziped the mattermail file and the config.json in that folder. Then I run into this:

root@mattermost:/opt# ./mattermail > /var/log/mattermail.log 2>&1
root@mattermost:/opt# ./mattermail
2016/10/06 15:46:04 Loading  ./config.json
2016/10/06 15:46:04 Could not parse: invalid character '/' looking for beginning of object key string

Something I'm missing here already?
My didn't change the config.json file for now, so the markup should be correct.

Create a filter rule with regex in subject

Hey,

I'm having the following problem:
I set up mattermail, but I'm not getting anything posted in the channel I configured and I added the user into. Here is my config file:
[ { "Name": "Info", "Server": "$server", "Team": "c3sidechannel", "Channel": "mail", "MattermostUser":"[email protected]", "MattermostPass":"password", "ImapServer": "mail.philmacfly.eu:143", "Email": "[email protected]", "EmailPass": "password", "MailTemplate": ":incoming_envelope: _From: **%v**_\n>_%v_\n\n%v", "StartTLS": true, "Disabled": false, "Debug": true } ]

I can only connect to IMAP Server with StartTLS when setting "TLSAcceptAllCerts": false

Error message is

Does this error message mean that mattermail cannot verifiy the server certificate?

The server is a public Server (mail.your-server.de, hosted by Hetzner in Germany) and has a valid certificate, openssl s_client -connect mail.your-server.de:143 -starttls imap works.

Version is Version: 4.0-dev, with same account mattermail was working fine (I think is was a 3.0-dev) before.

Hi,

whatever I do, it results in:

We couldn't find an existing account matching your credentials. This team may require an invite from the team owner to join.

My config is simple:

                "Server":        "https://mattermost.example.com",
                "Team":          "letstest",
                "Channel":       "rainertest",
                "MattermostUser":"rainer",
                "MattermostPass":"redacted",
                "ImapServer":    "mail.eample.com:993",

                "MailTemplate":  ":incoming_envelope: _From: **%v**_\n>_%v_\n\n%v"
        }
]

The URL for this channel is https://mattermost.example.com/letstest/channels/rainertest Do I have to put a #in front of the Channel name? (it does not work either)
raineris a member of this channel and can post from the web UI.
The installation is an omnibus bundled gitlab+mattermost, mattermost uses gitlab as OAuth provider

Hi,

I'm plagued by this error (usually it takes 2-4 weeks of run time to get to the point):
INFO Support 17:17:23 Connected with "imap-mail.outlook.com:993" INFO Support 17:17:33 Error on check new email: imap: command not allowed in the current state Try again in 30s INFO Support 17:18:03 Error Idle: imap: not available (IDLE) Try again in 30s

And it then repeats errors up until I stop it. Since the error start popping up in log no new e-mails are fetched from the inbox.

Any ideas why it is happening?

Right now it is hard coded to check every 30 seconds. Can you please make this an option that one can set in the config? Would greatly appreciate it :)

It's a bit tricky to get mattermail to start automatically as a service with systemd since the relative path ./config.json seems to be hardcoded into mattermail.

It would be nice to be able to supply an alternative configuration file path from the command line.

Hello,
I have a problem, all looks good that works, but in my log channel I can see an error:
Error on check new email: /users/login: , Post https://mydomain.com/api/v1/users/login: x509: certificate is valid for *.mydomain.com, not mydomain.com
All should works good and certifacate is for mydomain.com so I dont know why this doesnt work.
Also a link to download for version 3+ doesn`t work, you should make it available again :)
From this three links:

• http://yourserver.com/api/v1/admin/client_props
• http://yourserver.com/api/v3/admin/client_props
• http://yourserver.com/api/v3/general/client_props
  Only third show current config of my server.

thank you

Rodrigo,
This is a info request rather than a problem report. I was wondering how is handling for the original email content when someone replies to an email. Does the mattermail automatically strip off this content? (I have not yet tried using mattermail, just getting the mailbox ready for my test)

-Renjith

Would it be possible to assign direct message/channel using text from subject or body e.g:

Any message with subject line= "[bugs] this is a bug" would be assigned to bugs channel or subject line = "[user1] alert for user1 " would send direct message to user1?

Thank you for plugin.

Hey,

Could you please clarify with this below issue?

Error on check new email: imap: unexpected completion status ("NQYPO8 BAD Error in IMAP command FETCH: Invalid messageset")

Hi,

Do you think it is possible to evolve mattermail in a way that we can run it as a procmail filter?
Doing this way, no need to run the soft permanently, it is just run when a email arrives in the expected account.

Each emailed chat message always seems to get the email.html attachment, even if the email is "empty" (containing tiny html stub, possibly added by service like gmail, but no actual contents).

Please consider option where the whole email body/attachments can just be discarded, so that whole chat message might consist e.g. of just the subject.

Hi @rodrigocorsi2 ,

first of all: Thanks for this integration!

I´m having trouble posting to some channels, it´s a bit weird:
Channel 'testing': ok
Channel ' Town Square': INFO Mailgateway 21:15:06 Error on check new email: Did not find channel with name Town Square
Channel 'P1': same as Town Square.

The configured user has joined all channels, so that should be no problem.

As if it doesn´t like upper case letters...

Thanks,
Markus

Is it possible to define an smtp server for receiving new messages? Currently i get an error when using a non imap server.

I'm getting the following error after setting up mattermail:

would it be possible to add icomming webhook support? With gitlab as oauth provider, i do not have the possibility to create a MattermostUser/MattermostPassword

It is not possible to fetch longer emails. I want to display the whole email. I've sent a testemail with just one line: everything is finde

If I send a testemail with a little bit more lines:

I'm trying the option

"LinesToPreview": 100

According to my understanding, matternail is sending the message to only one User/ Channel.

If I am correct, is there any possibility to circulate a message with multiple Users/ Channels?

If possible, this regexp may be helpful.

^([a-zA-Z]*:)?\s*?\[\s*?([#@][A-Za-z0-9.\-_]*)\s*?(,|(\s*?|(\s*?and\s*?)|(\s*?or\s*?))[#@][A-Za-z0-9.\-_]*)*\s*?\]

There are some TLDs that are longer than the maximum of four letters. This leads to a failed config check.

If mattermail could be configured to pull email only from a specific folder(s) it could save having to set up a different email account for each different thing. This way can use already existing server side filtering software (like sieve or procmail) to filter the mail into the correct folder(s) without having to worry about writing our own filtering code in mattermail.

I am not sure how to describe the error any better. It gets all informaions from the IMAP server and team0 definitly exist but it prints that exact error. Posting the mail does not work.

I'm trying to dockerize this nice service, but there is something fishy going on.

I encounter the following issue when building mattermail:

• using go1.7.4 darwin/amd64 on OS X
• inside a alpine-golang:1.7.3 Docker container - here is the Dockerfile

➜  go get github.com/rodrigocorsi2/mattermail
# cd /Users/banzo/mattermail/src/github.com/rodrigocorsi2/mattermail; git submodule update --init --recursive
No submodule mapping found in .gitmodules for path 'vendor/github.com/alecthomas/log4go'
package github.com/rodrigocorsi2/mattermail: exit status 1

Note that cloning the repo using Sourcetree triggers a very similar error:

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree clone https://github.com/banzo/mattermail.git /Users/banzo/mattermail 
Cloning into '/Users/banzo/mattermail'...
warning: templates not found /usr/local/git/share/git-core/templates

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree submodule update --init --recursive 
No submodule mapping found in .gitmodules for path 'vendor/github.com/alecthomas/log4go'
Completed with errors, see above

Today there is no way to post in teams with ldap or oAuth.
One alternative is using webhook, but this is very limited because of filter rules and redirect by the subject.
Other way is create login alternatives by ldap and oAuth

I had a working configuration on ubuntu 14.04 x64. Had to move it (just copied folder) to a 12.04 x64, since then i get following errors when receiving mails:

Any ideas whats wrong?

Mattermost 3.5 is active

Don't receive emails from Gmail

Hey @rodrigocorsi2 !

First, hugely appreciate you sharing this project back with the world. Fantastic work!

I wanted to let you know about our plans moving to API v4:

To make the Mattermost API web service easier to use and to offer more powerful options for these integrations, Mattermost will be moving to a new API version soon. Highlights include:

• Fully documented API endpoints
• More in-depth access to server functionality
• Wider use of established HTTP verbs
• Consistent endpoint structures
• A new and improved Go driver

We plan to release API version 4 on March 16th, with Mattermost server 3.7. While the current API version 3 will be supported until September 16th, we recommend you begin using API version 4 soon after its release.

Contributing

API version 4 is an active and on-going project. If you're interested in helping contribute, please join our Mattermost community instance and the APIv4 channel.

We've prepared a contribution process for APIv4 and a progress tracker for new APIv4 enpoints to help you get started.

We're also open for suggestions on adding new API endpoints to help with your integration.

The error message is:

Hello.
I want to build your project in docker image. So in base image alpine i install go, git and build projects (also define GOPATH):
$ GOPATH=/home/mmail go get github.com/jhillyerd/go.enmime
$ GOPATH=/home/mmail go get github.com/mattermost/platform/model
$ GOPATH=/home/mmail go get github.com/mxk/go-imap/imap
$ GOPATH=/home/mmail go get github.com/paulrosania/go-charset/charset
$ GOPATH=/home/mmail go get github.com/paulrosania/go-charset/data

But, when i build mattermail i got the error:
$ GOPATH=/home/mmail go get github.com/rodrigocorsi2/mattermail

github.com/rodrigocorsi2/mattermail

src/github.com/rodrigocorsi2/mattermail/mattermail.go:308: client.UploadFile undefined (type *model.Client has no field or method UploadFile, but does have model.uploadFile)

The *linux.am64.tar.gz versions of 3.0.6 and 3.0.11 version packages seem to contain pre-built binary of 3.0.3 rather than binary matching the actual version.

Hi,

mattermail does log in successfully with username and password but has trouble to choose the correct team name. The code bails out differently when the password is wrong.

I suspect it is because the team name is "Familie Berger", i.e. having a space in between
