I'm running Postfix under Debian (Testing). At present I use an option in my mailer to translate my senders local address to the address I want but I'd prefer to have it done by Postfix. I want barry@localdomain to be translated to barry@beenthere-donethat.org.uk I looked through the Postfix documentation and assumed that I need to use the /etc/postfix/canonical file. I have tried the following entries: barry@localdomain barry@beenthere-donethat.org.uk @localdomain beenthere-donethat.org.uk None of these work. I still get the included sender address as barry@localdomain. I did remember to run postmap /etc/postfix/canonical and to be on the safe side I also ran postfix reload. Can anyone tell me what I'm doing wrong? Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain
