Hi there. I have had a virtual postfix/dovecot/procmail server set up for some time, and for the most part everything is working fine. The only quirk that I can’t figure out is some virtual aliases seem to fall through to the virtual domain’s catchall mailbox rather than getting delivered to the intended virtual user. Not sure if it’s my postfix or procmail settings.

I've included below what I think is the relevant parts of the relevant config files. If you need more, let me know.

What's happening is that mail getting sent to troy@example2.com.au gets correctly delivered to /var/mail/vhosts/example2.com.au/troy
But mail sent to one of the aliases like info@example2.com.au does not go to /var/mail/vhosts/example2.com.au/troy but rather /var/mail/vhosts

What am I missing?
