Password is correct.This happens with all accounts

Direct SMTP connection instead of php_mail() function

@fbartels I have changed the configuration in https://github.com/polytan02/z-push_ynh imap backend to use smtp with auth instead of php_mail() function.
This let us authenticate emails, which seems much better (it activates dkim, etc)

The config I use is as such :
polytan02@c39cb83
$imap_smtp_params = array('host' => 'ssl://DOMAINTOCHANGE', 'port' => 465, 'auth' => true, 'username' => 'imap_username', 'password' => 'imap_password', 'verify_peer' => true, 'verify_peer_name' => true, 'allow_self_signed' => true);

DOMAINTOCHANGE is transformed in domain.tld

But when I do that, I get some weird ERROR codes (but the email are sent and things look good...)

14/02/2017 00:57:00 [ 4554] [ERROR] [ben] trace error: /var/www/z-push/backend/imap/Mail/smtp.php:280 Only variables should be assigned by reference (2048) - backtrace: 6 steps

Would you have any idea of why it does that by any chance ?

lack of fail2ban support

The script do not include z-push fail2ban rules

Here, says how to do it... https://wiki.z-hub.io/display/ZP/Fail2Ban+support

I done it adding a file to /etc/fail2ban/jail.d
named z-push.conf

[z-push]
enable = true
port = http, https
filter = z-push
logpath = /var/log/z-push/z-push-error.log

with just that.. it works perfectly...

edit how verbose the log is ... is desirable too...
I've change /var/www/z-push/config.php, the line that said define('LOGLEVEL', LOGLEVEL_INFO); and put define('LOGLEVEL', LOGLEVEL_WARN); insted.

Hope this notes could be useful... it works OUT-OF-THE-BOX by default, but this 2 changes are very desirables....

problème de compte mail

Bonjour et merci pour le travail !

J'ai un problème quand j'ai un problème avec Z-PUSH sur mon serveur yunohost mes comptes mails sont formé comme cela :
[email protected]

quand j'envoi un mail depuis une machine qui passe par Z-push le mail de l'expediteur est [email protected]

j'ai l'impression que z-push utilise le nom du compte yunohost plutot que le compte mail.

J'ai essayé sur plusieur installations fraiches et j'ai toujours ce même problème. Pourtant quand j'essai avec roundcube j'ai bien la bonne addresse qui s'affiche chez mon ionterlocuteur.

Comment je peu corriger ça ?

Update to z-push 2.3.7

http://z-push.org/z-push-2-3-7-release/

Suggestion: Merge with tine20/syncroton

Hello,

First, let me tank you all for the continued efforts in maintain this fork of the original z-push.

I would like to suggest to @polytan02 and others that are actively contributing and developing this fork to merge the project with https://github.com/tine20/syncroton (or vice versa). Both projects are active but probably lack from contributions and the later one is working in ActiveSync v16 support.

This request also applies to @alecpl that seems to be the lead on syncroton.

Thank you all.

Forking Sogo

Hi,

Is it ok if i fork this and tweek it a little for Sogo and add it back with a new option that allows the user to choose sogo or baikal as an option?

here is the sogo installer i made if you wanna play with it https://github.com/mattronix/sogo_ynh

Blank page after Yunohost update

Hi,
I ran apt-get upgrade today and after updating Yunohost many apps were broken.
I almost fixed everything but Z-Push still does not working.
When I click on Z-Push app (https://myhost/Microsoft-Server-ActiveSync/) , I get a blank page.
Nothing in /var/log/z-push so I think that the problem is on Nginx.
I already tried to reinstall the app with :

# yunohost upgrade -u https://github.com/abeudin/z-push_ynh z-push

But it still does not working :(

In Z-Push 2.3.5 the path to AWL libraries is added to the include_path in imap.php

In Z-Push 2.3.5 the path to AWL libraries is added to the include_path in imap.php, so you shouldn't need the "ln -s ...".
As for the correct version I have no idea because it was Francisco Miguel Biete's contribution. It is an external library and we don't have control over it.

Baikal with Z-push with an android device

The installation of Z-push in combination with Baikal works very well. I try it on a virtual image hosting company with the standard SSL from letsencrypt. It works out of the box but there are some various problems:

• I can add various contacts and calendar events on the system with a program to read and write this to baikal.
• When i add my Android cellphone to the Z-push/baikal software it give some problems. The first synchronize try there was nothing to see in the calendar and addressbook list. But when i try it the second time it works. When i try to synchronize it again the calendar and addressbook are away again.
• When i try to add a new appointment or contact on my android smartphone it doesn't work. After synchronizing the contact and or appointment are away and it doesn't synchronize with baikal.

I try to install this 5 times on various servers and it never works...

In the error log i get the following error message:
20/11/2019 11:08:43 [ 1146] [WARN] [username] Mobile loop detected! Messages sent to the mobile will be restricted to 1 items in order to identify the conflict

How can i resolve this issue?

Calendar don't show evens from baikal

The calendar shows successful synchronization, but the calendar events are not displayed in calendar(calendar is empty).
The E-mail and contacts are working fine.

z-push seems unable to create mailboxes folders

z-push seems unable to create mailboxes folders. It means that you must send at least one email from roundcube or rainloop to have the mailboxes created. After than it all works fine.

I get the impression that the install script do not use $path at all ; could you confirm that @abeudin ?

Crash every night

Hi,
Z-push seems to crash every night on my yh server, I get this in logwatch :

499 (undefined)
   /Microsoft-Server-ActiveSync?jAAMBBAlSUA0L ... 8MlBNcVuA0DV1A4: 4 Time(s)
504 Gateway Timeout
   /Microsoft-Server-ActiveSync?jAAMBBAlSUA0L ... 8MlBNcVuA0DV1A4: 117 Time(s)

And my windows phone is not able to connect.
I have to restart my server to make it work.

Everything else works perfectly.
I had a look at nginx / php5-fpm / zpush logfile but I can't find any clue.

Do you have an idea ?

Xavier.

iPhone username instead of email regression
