Hello! Happy new year everyone. Postfix version 2.10.2.
I have a canonical maps configuration: recipient_canonical_maps = hash:/etc/postfix/rcptcanon Which contains one entry: @firstdomain.com @seconddomain.com The firstdomain.com and seconddomain.com are both virtual mailbox domains. The seconddomain.com has a single user, "test". If I send an email to he...@seconddomain.com, I get the following which is exactly as one would expect with the default recipient checking: 220 server ESMTP Postfix EHLO testing 250-server ... MAIL FROM: f...@thirddomain.com 250 2.1.0 Ok RCPT TO: he...@seconddomain.com 550 5.1.1 <he...@seconddomain.com>: Recipient address rejected: User unknown in virtual mailbox table QUIT 221 2.0.0 Bye However, if I send an email to he...@firstdomain.com, it sends successfully. A few minutes later I will then receive a bounce from the server: 220 server ESMTP Postfix EHLO testing 250-server ... MAIL FROM: f...@thirddomain.com 250 2.1.0 Ok RCPT TO: he...@firstdomain.com 250 2.1.5 Ok QUIT 221 2.0.0 Bye It seems that if an entry is found in recipient_canonical_maps, postfix assumes the target address to exist. Is this intended behaviour? Also, a secondary question I have regarding recipient_canonical_maps - is it possible to specify this under "-o" for smtpd, so it only performs the canonical on the way out/in? I can't see a way to do this. Thanks, Jason
