Hi! I'm trying to setup a simple backup mx on OpenBSD 5.8-stable, but so far it seems more of a burden than a "simple" task :)
smtpd.conf: ------------------------8<------------------------ pki hostname certificate "/etc/ssl/smtpd_cert.pem" pki hostname key "/etc/ssl/private/smtpd_key.pem" listen on pppoe0 tls pki hostname table aliases db:/etc/mail/aliases.db accept for local alias <aliases> deliver to mbox accept from any for domain "example.com" relay backup tls verify expire 30d accept from local for any relay ------------------------8<------------------------ The MX records are set for example.com correctly, with the priority set to 10 for the primary MX, and 20 for this, the secondary. The $(hostname) is the same as in the MX record. So what this configuration does currently, is it loops the mail back to itself [1], like it had never done an actual MX lookup for example.com, and determined that there are MX servers with higher priority to relay the mail to. I thought it would work like this: -> accepting the mail from outside of the box, if the rcpt is the domain @example.com -> DNS lookup for MX record, check if there are higher priority servers -> relay mail to MX server with higher priority ... -> ... otherwise if it cannot do it, queue it for 30 days. Clearly I am missing something, but what?
