I pointed a new subdomain where I want all email to be sent to a particular program.
So, I setup that program as an mta. I can't get the smtpd mta action to work in smtpd. Take a look: table listdomains { lists.nmedia.net } action list_mda mda "/usr/local/bin/list-mda %{rcpt}" match from any for domain <listdomains> action list_mda When the DNS record is in place, email to l...@lists.nmedia.net results in 500 5.4.6 Routing loop detected: Loop detected It does not ever execute /usr/local/bin/list-mda I really don't understand how to use the mda feature. Can someone please clue me? Do I need to create some kind of fake alias or user to prevent the loop?
