Hi, I'd like some explanation on how opensmtpd works as a backup mx. I use opensmtpd-201405202105p1 compiled myself on Debian7.
First I had "accept from any for domain "dom.fr" relay backup" in my config file. But after a few minutes I get a message back complaining that there is a loop. No, this can't be. mx1 (weight 5) isn't the same as mx2 (weight 10). So I went with "accept from any for domain "dom.fr" relay backup mx2.backdom.fr" so it never tries to deliver to mx2 again (if I get the man right). Why do I have to specify the mx, what is the point ? From my point of view, a backup mx MUST (as in RFC MUST) always try to deliver to a lower pref mx thank itself and keep it until it can deliver (or timeout). So after adding the mx to backup, I don't have the loop-error but opensmtpd tries to deliver not to mx1.domain.tld but to domain.tld (which doesn't exist). I had to add a A record to have mails delivered. $ host dom.fr dom.fr mail is handled by 5 mx1.dom.fr. dom.fr mail is handled by 10 mx2.backdom.fr. dom.fr mail is handled by 15 mx3.backdom2.fr.
