Hi list, My Postfix 3.2.4 server is not a MX for domainB. domainB is not in virtual_mailbox_domains.
it is a MX for domainA which is in virtual_mailbox_domains. I have in my ldap some users with: mailAlternateAddress=user@domainB my virtual_alias_maps ldap query filter is: (|(mail=%s)(mailAlternateAddress=%s)) And the result attribut is "mail" (always in @domainA). The problem is that if I send email to user@domainB from mynetworks or being sasl_authenticated the email is locally delivered (in the log: to=user@domainA , orig_to=user@domainB). I've tried to add in transport: domainB relay:mx.domainB But it's not working :( postconf -n: https://pastebin.com/NJ1TuzhP Thanks for any help, kfx
