[SOLVED] Integration with Mailman

[amitbapat]

I am trying to integrate Zimbra Postfix with Mailman and I'm stuck.

Here is an excerpt from Mailman installation guide :

First, you need to set up the Postfix virtual alias domains as described in the Postfix documentation (see Postfix's virtual(5) manpage). Note that it's your responsibility to include the virtual-alias.domain anything line as described manpage; Mailman will not include this line in virtual-mailman. You are highly encouraged to make sure your virtual alias domains are working properly before integrating with Mailman.

I know that there is already a virtual_alias_maps table setup (with ldap lookup, in Zimbra Postfix). What I could not understand is the comment about "virtual-alias.doman anything" entry.

Has anybody tried integrating mailman with Zimbra?

[amitbapat]

I have added following to main.cf of postfix:

virtual_alias_maps = ldap:/opt/zimbra/conf/ldap-vam.cf,hash:/etc/mailman/virtual-mailman
alias_maps = hash:/etc/aliases,hash:/etc/mailman/aliases

/etc/mailman/virtual-mailman contains:

testlist@domain.com              testlist
testlist-admin@domain.com        testlist-admin
testlist-bounces@domain.com      testlist-bounces
testlist-confirm@domain.com      testlist-confirm
testlist-join@domain.com         testlist-join
testlist-leave@domain.com        testlist-leave
testlist-owner@domain.com        testlist-owner
testlist-request@domain.com      testlist-request
testlist-subscribe@domain.com    testlist-subscribe
testlist-unsubscribe@domain.com  testlist-unsubscribe

/etc/mailman/aliases contains:

testlist:             "|/usr/lib/mailman/mail/mailman post testlist"
testlist-admin:       "|/usr/lib/mailman/mail/mailman admin testlist"
testlist-bounces:     "|/usr/lib/mailman/mail/mailman bounces testlist"
testlist-confirm:     "|/usr/lib/mailman/mail/mailman confirm testlist"
testlist-join:        "|/usr/lib/mailman/mail/mailman join testlist"
testlist-leave:       "|/usr/lib/mailman/mail/mailman leave testlist"
testlist-owner:       "|/usr/lib/mailman/mail/mailman owner testlist"
testlist-request:     "|/usr/lib/mailman/mail/mailman request testlist"
testlist-subscribe:   "|/usr/lib/mailman/mail/mailman subscribe testlist"
testlist-unsubscribe: "|/usr/lib/mailman/mail/mailman unsubscribe testlist"

$myhostname is "linux.lan" which is not a FQDN. I am hosting domain.com and domain2.com as two virtual domains. "linux.lan" is also added as domain in zimbra.

testlist@domain.com gets correctly translated to testlist@linux.lan because of virtual_alias_map entry in the 'virtual-mailman' file.

However, instead of delivering "testlist@linux.lan" locally using the alias_maps, postfix bounces it.

What am I doing wrong?

[marcmac]

What's it logging when it bounces the message? Do you have dns enabled?

I have fudged email address to protect privacy.
sender@wundermail.com is the sender from outside.
testlist@domain.com is the mailing list I have created in mailman as described in the first post.

[marcmac]

And, do you have DNS enabled on the MTA?

[amitbapat]

I am running a local DNS server for .lan zone on another linux machine on the intranet. This DNS also works as a cacheing name server.
Here's linux.lan's /etc/resolve.conf

search lan
nameserver 192.168.11.1

Running dig on linux.lan would yield following:

If you want to send mail to the domain, you should add an MX record to your DNS server.

Also - does this account testlist@linux.lan exist anywhere?

[amitbapat]

No testlist@linux.lan only exists in the virtual_alias_maps, that is /etc/mailman/virtual-mailman.

Let me try adding MX to my DNS and see.

[amitbapat]

I really don't need to receive mail for linux.lan. All my real accounts are on domain.com and domain2.com. I only created linux.lan domain in Zimbra because that was the default option when I installed.

What if I remove the linux.lan domain from zimbra and move the Zimbra SPAM and Zimbra HAM account from the linux.lan domain to domain.com?

Will that force postfix to deliver mail for linux.lan locally? Because then there would be no entry for linux.lan in virtual_mailbox_domains and postfix will be forced to use local_recipient_maps to deliver.

Here's my thinking, let me know if it is correct:

on a RCPT TO: address, postfix searches virtual_alias_domains, virtual_mailbox_domains. Since linux.lan won't be there it'll try to match it to myhostname which happens to be linux.lan so it'll match.

and since local_transport is set to local:$myhostname, now postfix will be forced to deliver testlist@linux.lan locally.

Is that correct?

[marcmac]

afaik, that's correct. I assume that it's bouncing it because there's no such account in it's recipient table (in ldap).

So, I'm not sure what kind of expansion testlist@linux.lan is supposed to undergo, or where the email is ultimately supposed to be delivered - but it appears that that expansion is not happening.
