[Mailman-Users] Virtual Domains stopped working

[Jan Steinman]

Environment: MacOS X 10.6.8 server on Mac Mini, Mailman v2.1.14, as supplied with MacOS X. I have a main MX mail server (mail.bytesmiths.com) and a number of other domain names, all sharing the same static IP. I run my own DNS, with all domains pointing MX records to mail.bytesmiths.com. Each of these domains have one or more mailman lists that were working properly a few days ago.

I added a new list to one of the domains (ecoreality.org) using the Mailman web interface. Then all my lists stopped working, with error messages like:
	<List_that_belongs_to_another_domain at bytesmiths.com>: user unknown

(I thought just the new one wasn't working, until someone forwarded me the reject notice they got when they tried to post to a list.)

/etc/postfix/main.cf refers to two mailman files:
	virtual_alias_maps = hash:/etc/postfix/virtual,hash:/var/mailman/data/virtual-mailman,hash:/etc/postfix/virtual_users
	alias_maps = hash:/etc/aliases,hash:/var/mailman/data/aliases

I went into /var/mailman/data and noticed that "aliases" was newer than "aliases.db". So in what was perhaps a foolish shot in the dark, I did "postmap aliases" and "postmap virtual-mailman" to refresh the .db files, but to no avail.

I can still get in the admin pages for the lists I administer, and I'm still getting subscription notifications via web sign-up, but sending out through at least several of the lists I've tried all fail.

Any clues what I can do to fix this? I'm fairly competent and happy to be pointed in the right direction.

Thanks!
