HI, I've set up a domain with a catch-all to deliver emails to any address to a single recipient address by specifying it in my virtual_alias_maps. However, the user wants to be able to send mail as any user in that domain. The problem is that it's rejected with "sender address rejected" because the user isn't defined in the smtpd_sender_login_maps.

I also thought of using the recipient_delimiter, so sending something like user1+a...@mydomain.com might work, but it's not what was asked for. Maybe this is a dovecot config option I'm missing? Thanks for any ideas on what I'm missing here.
