SMTP Banner missing

[delijati]

Hi i have two question reagrding the main.cf file.

• How can i add the smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
• When i edit the HOSTNAME in mailu.env the entry myhostname is still the old one. Can i trigger the creation of that file. [1] I tried docker container prune and this files is also not in /mailu

[1]

foo:/mailu$ docker-compose exec smtp bash -c "cat /etc/postfix/main.cf | grep myhost"
myhostname = mail.foo.de
foo:/mailu$ cat mailu.env | grep HOS
HOSTNAMES=mail.foo.de,foo-de.foo.de

Using mailu 1.7

Ok adding HOSTNAME won't work as of https://github.com/Mailu/Mailu/blob/master/core/postfix/conf/main.cf#L10

I tried overwrites:

$ cat overrides/postfix.cf 
smtpd_banner = foo-de.foo.de ESMTP Postfix (Alpine)
# and
$ docker-compose exec smtp bash -c "postconf | grep banner"
postscreen_greet_banner = $smtpd_banner
smtpd_banner = foo-de.foo.de ESMTP Postfix (Alpine)

But i still get:

$ echo QUIT|nc foo.de 25
220 mail.foo.de ESMTP ready
221 2.0.0 Bye

Ok i also tested master but still have the same problem with not being able to set the SMTP Banner

It seams the BANNER is set by NGINX ... I changed [1] and it worked. So the overwrites in postfix.cf are complete ignored. This should go to the FAQ ;)

$ cat mailu.env | grep HOST
HOSTNAMES=foo-de.foo.de,mail.foo.de
$ sudo docker-compose stop
$ sudo docker-compose up -d
$ echo QUIT|nc foo.de 25   
220 foo-de.foo.de ESMTP ready
221 2.0.0 Bye

Hi There,

The Mailu-Project is currently in a bit of a bind! We are short on man-power, and we need to judge if it is possible for us to put in some work on this issue.

To help with that, we are currently trying to find out which issues are actively keeping users from using Mailu, which issues have someone who want to work on them — and which issues may be less important. These a less important ones could be discarded for the time being, until the project is in a more stable and regular state once again.

In order for us to better assess this, it would be helpful if you could put a reaction on this post (use the 😃 icon to the top-right).

• 👍️ if you need this to be able to use Mailu. Ideally, you’d also be able to test this on your installation, and provide feedback …
• 🎉 if you find it a nice bonus, but no deal-breaker
• 🚀 if you want to work on it yourself!
  We want to keep this voting open for 2 weeks from now, so please help out!

220 foo-de.foo.de ESMTP ready

So to clear this up I should change the order of the HOSTNAMES var to place the smtp[.example.com] alias first instead of the mail[.example.com] ou whatever was there?
