How to add second smtp user?

I want to have multiple smtp user, how to achive this?

timeout

I was wondering if anyone has noticed timeout errors in /var/log/mail.log when sending mail:

Mar 23 11:21:31 886377d1c5cf postfix/smtp[143]: connect to pb-mx13.pobox.com[64.147.108.54]:25: Connection timed out

I see the same thing when sending to gmail addresses.

I'm running with docker-compose:

  mail:
    restart: always
    image: catatnight/postfix

    environment:
      - "maildomain=localhost"
      - "smtp_user=test:testpass"

TLS required anyway

If i send any mail through port 25, postfix required a TLS certificate, is possible disable the TLS authentication?

Timezone

The default timezone is UTC and my tz is America/Sao_Paulo, how about to select timezone when creating the docker?

Usage 1 example failes

Referring to your first example:

sudo docker run -p 25:25 \
        -e maildomain=mail.example.com -e smtp_user=user:pwd \
        --name postfix -d catatnight/postfix

If I run that it fails with this in docker logs:

docker logs deployment_postfix_1
find: `/etc/postfix/certs': No such file or directory
find: `/etc/opendkim/domainkeys': No such file or directory
Error: The directory named as part of the path /var/log/supervisor/supervisord.log does not exist.
For help, use /usr/bin/supervisord -h

Note I actually run it using this fig configuration:

postfix:
  image: catatnight/postfix
  hostname: postfix
  environment:
    # You could change this to something more suitable
    - maildomain=kartoza.com
    - smtp_user=noreply:docker
  volumes:
    - ./logs:/var/log

multiple domain

How can i set multiple domain?

Thanks

Security Updates

On docker hub this image hasn't been updated in years. At minimum I'd recommend a 30 day curl call to rebuild to handle security updates.

app.ERROR: Exception occurred while flushing email queue: Connection could not be established with host

Hello, could you please provide some help?

I've got a project on SF4. KVM virtual server and docker. I use this docker image. When i connect to container and run postfix check - everything is ok, but from the project it does not want to send email with error

app.ERROR: Exception occurred while flushing email queue: Connection could not be established with host smtp.******.ru

Image does not work with docker-compose

The ports are not exposed properly when starting the container through docker-compose.

Issues emailing office365

Just wanted to give you a heads up that emailing something that is hosted at office365 will fail with:

454 4.7.0 Failed to establish appropriate TLS channel: Access Denied (in reply to RCPT TO command))

I was able to fix this by adding the following to main.cf:

smtp_tls_security_level = may

volume for mail queue

You don't want to trash your mail queue when you rebuild your container.

Maybe this can be treated by documentation alone.

authentication failed: another step is needed in authentication

hello, i started the container with command docker run -it --rm -p 25:25 -e maildomain=xjplus.xyz -e smtp_user=test123:test123 --name tmpp catatnight/postfix,
then test it with telnet as below and i got authentication failure, what's wrong with that?
isn't sasl used at auth login? look for help, 3q..

Questions, student requesting for help

I'm trying to find a smtp server to send verification emails for my homework at college. I don't know if I come to the right place. I've built the image and have it run. I wonder if I need extra steps to have it send mails, for example DNS (actually I've tried this, still not work)?

I am using flask-mail to test. The message returned shows that authentication has been passed and that the mail has been queued, but, I still cannot receive the email. Here's the message, although by flask-mail, hopefully it can help:

TLS with outgoing connection

Hi. Please add TLS for outgoing connection so gmail will stop indicate emails as "not encrypted"
smtp_use_tls=yes -> /etc/postfix/main.cf
