Cannot use mailing lists with non-primary domain

g1smo commented 3 years ago

Describe the bug

When trying to use a secondary domain on our yunohost installation for a mailing list, 550 mailbox not available is replied every time.

Context

Hardware: LXC container in physical machine I am maintaining
YunoHost version: 4.2.8.3
I have access to my server: Through SSH, through the webadmin, direct access via keyboard / screen
Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes We are using a secondary domain for emails and some sites. The domain is managed by Yunohost and works for user accounts' individual mailboxes. There is an additional site configured in mailman3 and an additional domain name configured for that site.

Our primary domain is kompot.si and the secondary one lom.je.

Steps to reproduce

Add a secondary domain's site and domain in mailman3 administration panel, create a new mailing list, send email to it.

Expected behavior

Recipients of the mailing list should receive the mail

I can add some additional configuration files.

Multiple mailing lists on our primary kompot.si domain are working flawlessly.

Hey, don't know if it helps but I had a simliar issue: Did you follow the instructions in the Readme at "Configure incoming mail"? In /etc/postfix/main.cf I just had to add hash:/var/lib/mailman3/data/postfix_lmtp to this line: virtual_mailbox_maps = ldap:/etc/postfix/ldap-accounts.cf

I'm no expert here, but thought it be the same thing?

Hey,

Yes, I had to add that to get mailing lists working in the first place:

virtual_mailbox_maps =
        hash:/var/lib/mailman3/data/postfix_lmtp,
        ldap:/etc/postfix/ldap-accounts.cf

I moved postfix_lmtp above ldap accounts, since, otherwise, adding a mail alias for a user could "trump" the mailing list address. Since we're not using a subdomain for lists.

The non-primary domain still doesn't work...

I had a similar setup and the same issue. It seems mailman3 does not like to have multiple mail hosts pointing to identical alias domains. I was able to solve it by using different alias domains for each mail host. In your case that'd be 1.yunohost.org and 2.yunohost.org instead of yunohost.org. I think this is probably a bug in mailman3 but I have not looked into it any deeper.
