Topic: Cannot receive email

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version: 0.9.9 MYSQL edition.
- Deployed with the downloadable installer.
- Linux/BSD distribution name and version: Ubuntu 16.04 LTS
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro?: Nope
====

So basically I setup the server with the installer and the logs don't show any issues. I created a new user and sending mail works fine. However receiving email fails. The /var/log/mail.log shows me the following error:

to=<postmaster@MYDOMAIN.COM>, relay=dovecot, delay=1478, delays=1478/0/0/0.04, dsn=4.3.0, status=deferred (temporary failure. Command output: lda(postmaster@MYDOMAIN.COM,)Error: Error reading configuration: Invalid settings: postmaster_address setting not given lda: Fatal: Internal error occurred. Refer to server log for more information. )


I tried searching the forums and the rest of the internet but I cannot find a working solution. Anyone with tips?

Re: Cannot receive email

Comment out or remove "postmaster_address =" in /etc/dovecot/dovecot.conf, restart Dovecot service and try again.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Thank you for the response ZhangHuangbin. I've seen the same suggestion on the forum before and can assure you that my config does not contain the "postmaster_address = " line.

Do you have any other suggestions? Or could you maby explain why the line is not supposed to be there since the error states it should be?

Re: Cannot receive email

Okay I managed to fix the first issue. Turn out that my hostname was reverted after a reboot. I now no longer get the error mentioned above.

I'm now at the following error:
mx dovecot: lda(postmaster@MYDOMAIN.COM): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=2000(vmail) egid=2000(vmail) UNIX perms appear ok (ACL/MAC wrong?), dir owned by 0:0 mode=0755)

EDIT:
I managed to fix the second issue as well.
In the file: /etc/apparmor.d/usr.lib.dovecot.dovecot-lda

I changed the line:
/usr/lib/dovecot/dovecot-lda flags=(complain) {

Into the line:
/usr/lib/dovecot/dovecot-lda flags=(complain,attach_disconnected) {

After that a restart of the apparmor service fixed the issue.
