Hi, I've been running postfix as my MTA for many years. Recently I upgraded my main server and now I cannot send mail anymore.
The system is running Fedora 13, with postfix 2.7.0 (postfix-2.7.0-1.fc13.i686). My previous version of postfix was 2.5. I have a LAN with local DNS that is connected via ADSL to the internet. As far as the outside world concerns there's only a single host connected. The output of 'postconf -n' is attached at the end of this message. The problem: although I have configured mydomain = squirrel.nl myorigin = squirrel.nl postfix stil uses the real, local hostname in the SMTP envelope: > EHLO phoenix.squirrel.nl < 250-smtp-vbr12.xs4all.nl Hello sioban.squirrel.nl [80.101.24.220], pleased to meet you < 250-ENHANCEDSTATUSCODES < 250-PIPELINING < 250-8BITMIME < 250-SIZE 31457280 < 250-DSN < 250-AUTH LOGIN PLAIN < 250-STARTTLS < 250-DELIVERBY < 250 HELP server features: 0x901f size 31457280 Using ESMTP PIPELINING, TCP send buffer size is 4096 > MAIL FROM:<j...@phoenix.squirrel.nl> SIZE=694 As you may have guessed, phoenix.squirrel.nl is a local hostname and not known in the outer world. The xs4all mail server therefore rejects the mail with 553 5.1.8 j...@phoenix.squirrel.nl... Domain of sender address j...@phoenix.squirrel.nl does not exist Since I did not have any problems with outgoing mail before the upgrade to 2.7 I'm pretty sure that in the older version of postfix myorigin was applied to the SMTP envelope too, I temporarily 'fixed' the problem by adding a CNAME for phoenix in the global DNS but that's not a good solution. Did I overlook a (new?) config setting?
