Mail for root not received after latest updates

NethServer Version: V7
Module: mail

Following the updates a few days ago, I am no longer receiving mail from one of my VMs addressed to root. Here’s the maillog for one of the attempts:

Jul  3 03:20:40 Nethserver postfix/smtpd[21511]: connect from FortKnox.BogoLinux.net[192.168.0.100]
Jul  3 03:20:40 Nethserver postfix/smtpd[21511]: NOQUEUE: client=FortKnox.BogoLinux.net[192.168.0.100]
Jul  3 03:20:40 Nethserver postfix/smtpd[21511]: warning: connect to proxy filter 127.0.0.1:10024: Connection refused
Jul  3 03:20:40 Nethserver postfix/smtpd[21511]: proxy-reject: END-OF-MESSAGE: 451 4.3.0 Error: queue file write error; from=<root@fortknox.bogolinux.net> to=<root@nethserver.bogolinux.net> proto=SMTP helo=<fortknox.bogolinux.net>
Jul  3 03:20:40 Nethserver postfix/smtpd[21511]: disconnect from FortKnox.BogoLinux.net[192.168.0.100]

The listener for port 10024 is a little different than the other tcp6 ones:

[root@Nethserver ~]# netstat -an | grep LISTEN\  | grep tcp6
tcp6       0      0 ::1:10024               :::*                    LISTEN
tcp6       0      0 :::587                  :::*                    LISTEN
tcp6       0      0 :::110                  :::*                    LISTEN

Note the extra “1”.

Is this the reason and how can I fix it.

** UPDATE **
Possibly not the reason, as well as amavisd (10024 above), spamd (783) and unbound (8953) also use the same addressing.

Cheers.

Please have a look at 127.0.0.1[127.0.0.1]:10024: Connection refused | Howtoforge - Linux Howtos and Tutorials
Perhaps one of this tips could help you.

Previous to the last updates I was receiving mail correctly. I do not, and have not, modified any of the configuration files involved in the mail delivery.

Pointing me at a thread that implies amavisd is not running does not help, as my post clearly shows that port 10024 is in listening mode.

Cheers.

Did you read this?

Have the same issue:
Dec 19 15:23:56 sd postfix/smtp[179]: BFE3738054E: to=the@mail.com, relay=none, delay=0.14, delays=0.13/0.01/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)


>postfix and amavisd-new are started.
>Restart amavisd and if it does not start, check the mail.log file for the reason.
>I did this earlier: In /etc/clamav/clamd.conf AllowSupplementaryGroups false -> true
But then I didn't restart it... So: service clamav-daemon restart Solved the issue.

PS: I only tried to help, it’s not my area of expertise.

Please confirm that amavisd is working on port 10024 with the following command:

$ nc localhost 10024
220 [127.0.0.1] ESMTP amavisd-new service ready

If it doesn’t, try to restart the service (through server-manager or systemctl restart amavisd
If the restart fixes, please search /var/log/maillog for amavisd restarts in the past (maybe close in time to the update).
Let us know, please.

I’ll keep an eye on this:

[root@Nethserver ~]# netstat -an | grep 10024
tcp6       0      0 ::1:10024               :::*                    LISTEN
[root@Nethserver ~]# nc localhost 10024
Ncat: Connection refused.
[root@Nethserver ~]# systemctl restart amavisd
[root@Nethserver ~]# netstat -an | grep 10024
tcp        0      0 127.0.0.1:10024         0.0.0.0:*               LISTEN
tcp6       0      0 ::1:10024               :::*                    LISTEN
[root@Nethserver ~]# nc localhost 10024
220 [127.0.0.1] ESMTP amavisd-new service ready

I only get a couple of messages each day, both early morning and the last received were July 2. I’ll check again tomorrow.

Cheers.

OK, so after today’s updates and re-boot, I now have this:

[root@Nethserver ~]# netstat -an | grep 10024
tcp        0      0 127.0.0.1:10024         0.0.0.0:*               LISTEN
[root@Nethserver ~]#

So, what it looks like happened was that after the re-boot for the previous updates, amavisd started on the IPv6 listener instead of the IPv4. The restart I did mid re-boots, based on the earlier replies, correctly, started it on the IPv4 which made everything work fine.

Wonder why the previous re-boot picked the wrong protocol.

Cheers.

If you have solved it, please mark your answer as solution.

IMO his issue is resolved, but the reason why he had such an issue must be investigated

amavisd has been recently updated to run better under systemd (which is our/centos7 case).
I don’t know if it may have solved this issue.
I see
After=network.target
in amavisd systemd startup script.
