Problem sending mailing list with Mailman, postfix, centos 6.5

[IssueMan]

Dear Parallels,

we are in this situation:

OS: CentOS 6.5 (Final)
Plesk version: 12.0.18 Update #16, last updated at Sept 11, 2014 04:07 AM
PHP: 5.4.32

we created a new mailing list [email protected] and we tried to send a message, as administrator, to the list and to the temporary users subscribed.

But Mailman dones't send anything ! And we receive this error:

Sep 11 15:20:00 2014 (30314) All recipients refused: {'[email protected]': (554, '5.7.1 <[email protected]>: Relay access denied')}, msgid: <[email protected]>
Sep 11 15:20:00 2014 (30314) delivery to [email protected] failed with code 554: 5.7.1 <[email protected]>: Relay access denied
Sep 11 15:20:00 2014 (30314) SMTP session failure: 550, 5.7.1 Command rejected, msgid: <[email protected]>

Can you tell us why this problem ????

All other services on this server seems to be ok, normail email sending, receiving, http... all right... but mailman no.

thank you.

I hope that this KB article will help - http://kb.odin.com/121952

Thanks, I'm looking at the KB article now.
The mchk utility says that everthing is ok, except for "Checking for: mail_drweb_restore... not found, skipped".

Anyway, the KB article seems related to problems with relay to mailboxes on the same server and "only occurring for mail accounts within a specific domain", but as previously stated in our situation Mailman doesn't send any mail, both to mailboxes on the same server and to external ones.

Some lines from the maillog related to the situation ("[email protected]" is on an external server):

Sep 12 01:49:10 dns5 postfix/smtpd[27165]: connect from localhost[::1]
Sep 12 01:49:10 dns5 postfix/smtpd[27165]: NOQUEUE: reject: RCPT from localhost[::1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<localhost.localdomain>
Sep 12 01:49:10 dns5 postfix/smtpd[27165]: disconnect from localhost[::1]

Sep 12 01:49:10 dns5 spf filter[27254]: Wrong HELO hostname: localhost.localdomain

Sep 12 01:49:10 dns5 postfix/cleanup[25481]: 87BB47C95: milter-reject: END-OF-MESSAGE from localhost[::1]: 5.7.1 Command rejected; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<localhost.localdomain>


It seems to me that the spf filter doesn't like "localhost.localdomain", but I'm not sure how to change it for the messages sent by Mailman.


Thank you for any suggestion.

Hi IssueMan,

I had the same (or similar) error. Mailman just delivered mails to local, not to external!

I had to edit: /etc/postfix/main.cf

# I changed mynetworks = , [::1]/128 to
mynetworks = 127.0.0.0/8, <yourServerIP>/32

After reloading postfix, my mailman is sending again! Hope it helps you (or some one else who runs into that problem)
