Presumably you are posting to this list because the systems running the cron jobs have Postfix as their MTA. > unfortunately the hosts sending the mail announce themselves as > [email protected] which is being rejected by our exchange server > (sender address rejected: domain not found) What you mean by "announce themselves".

Pick one or the other. Regular expression tables OR indexed tables with fixed lookup keys. In this case, since the domain will match $myorigin, fixed keys make more sense: root [email protected] See a more complete example in http://www.postfix.org/MULTI_INSTANCE_README.html#quick > > I can check this with the following command... > > postmap -fq "[email protected]" regexp:/etc/postfix/generic What is the setting of smtp_generic_maps reported by "postconf -n". > > ...it does indeed attempt to get delivered to the [email protected] address (so > the entry in aliases is fine) but the sender does not get translated - it > still presents as "[email protected]" > > what am I doing wrong ? Probably using "hash:/etc/postfix/generic" in main.cf, when "regexp:" is what you tested. That said, the regexp thing is unwise, there are better ways of doing this. -- Viktor.
