Topic: 4 new domain + 4 users is rejected missing dovecot relay or transport.

Hi ..

Today I have created 4 new domains and in each of them 1 user account. Nothing went wrong in the gui when doing so. Have done that alot of time. But this is the first time after the last upgrade.

I dont say that the upgrade is the problem - only trying to explain..

- iRedMail version: iRedAdmin-Pro v1.6.2 (LDAP)
- Linux/BSD distribution name and version: Debian 5.0.8

My mail.log is saying af following:

Oct  4 18:04:20 mail postfix/qmgr[2786]: warning: connect to transport private/dovecot,dovecot: No such file or directory
Oct  4 18:04:20 mail postfix/error[3513]: 44A64EC201: to=<xx@x-xxxx.xx>, relay=none, delay=0.6, delays=0.57/0.01/0/0.02, dsn=4.3.0, status=deferred (mail transport unavailable)

xx@xxxx.xx is replaced characters..

What I have tried so far. Restarted server. Removed dovecot from the relay in domain settings, saved, tested and nothing. Putting dovecot back in, save and tested - and nothing.

Anyone with a solutions or some info/hints on that to try next.

Thanks in advance

Regards

It means Postfix cannot connect to Dovecot socket file /var/spool/postfix/private/dovecot.
Was Dovecot running as expected? Could you please post output of below commands to help troubleshoot?

# dovecot -n
# postfix -n

Re: 4 new domain + 4 users is rejected missing dovecot relay or transport.

I saw you have below setting in Postfix, which is incorrect:

smtpd_sasl_path = private/dovecot-auth

Default setting in iRedMail is:

smtpd_sasl_path = ./dovecot-auth

In maillog, it shows:

Oct  6 07:20:39 mail postfix/qmgr[2781]: warning: connect to transport private/dovecot,dovecot: No such file or directory

It means this user has incorrect per-user transport. Could you please paste LDIF data of this account here to help troubleshoot? You can export LDIF data of this account by accessing iRedAdmin-Pro-LDAP:
https://your_server/iredadmin/export/ldif/user/user@domain.ltd (Replace "user@domain.ltd" with real email address)

Warning: Please do remove sensitive infomation in LDIF before posting.

Re: 4 new domain + 4 users is rejected missing dovecot relay or transport.

After checking your "dovecot -n", i found you have different settings with iRedMail default settings:

Yours:

  socket:
    type: listen
    client:
      path: /var/spool/postfix/private/dovecot-auth
      mode: 438
      user: postfix
      group: postfix
    master:
      path: /var/run/dovecot/auth-master
      mode: 438
      user: vmail
      group: vmail

In iRedMail, it should be:

socket:
    type: listen
    client:
      path: /var/spool/postfix/dovecot-auth
      mode: 0666
      user: postfix
      group: postfix
    master:
      path: /var/run/dovecot/auth-master
      mode: 0666
      user: vmail
      group: vmail

Re: 4 new domain + 4 users is rejected missing dovecot relay or transport.

Hi ZangHuangbin ..

First - Thanks for your help so far ..

Now - I cant simply find anywhere i files mode = 0438 - all places I only see mode = 0666 .. If not in /etc/dovecot/dovecot.conf files where could that info else come from?

LDIF shows for one of the 4 new account the following:

Your dovecot.conf should have settings like below:

auth default {
    [...OMIT OTHER SETTINGS HERE...]

    socket listen {
        master {
            path = /var/run/dovecot/auth-master
            mode = 0666
            user = vmail
            group = vmail
        }
        client {
            path = /var/spool/postfix/dovecot-auth
            mode = 0666
            user = postfix
            group = postfix
        }
    }
}

As mentioned in my previous reply, please make sure you have correct settings in Postfix and Dovecot. If it doesn't work, post output of command "dovecot -n" and "postconf -n" here to help troubleshoot.
