Hi, I'm having some trouble with my production server, that mailman
stopped working apparently without any modification. I think
everything at my postfix configuration is ok, but what I'm seeing is
that virtual_alias_maps isn't working as expected.
My setup consists in one virtual domain example.com and some
"accounts" from this domain are lists, like samplelist(a)example.com
According to postfix flow, if I send an e-mail to
samplelist(a)example.com it will match the line
hash:/var/lib/mailman/data/virtual-mailman in my virtual_alias_maps
and returns samplelist, then it's expected to match samplelist at line
alias_maps = hash:/var/lib/mailman/data/aliases and pipe the e-mail to
"|/var/lib/mailman/mail/mailman post samplelist", but instead postfix
is just sending the e-mail to maildrop with destination like one of my
regular accounts, then maildrop is returning user unknown, of course
because samplelist(a)example.com isn't a valid user account.
I don't know why postfix isn't matching alias_maps to pipe the mail to mailman.
Someone could help me?

Thanks!

The result addresses above should include a domain listed in
mydestination.

samplelist(a)example.com samplelist(a)localhost.example.com
....

mydestination = localhost.example.com ...
