Take a look at this: http://www.postfix.org/ADDRESS_REWRITING_README.html There are a lot of examples and you'll find what you're looking for.
If you want to change the domain for incoming and outgoing e-mails you can do this with canonical_maps. If you only want to apply the rules for incoming mails, use recipient_canonical_maps or for outgoing mails sender_canonical_maps. The table/file you define after the parameter can contain the complete domain name (as wildcard) or full e-mail address which you want to rewrite: canonical_map: @abc.net @abc.org <- for all e-mail addresses of abc.net ma...@abc.net ma...@abc.org <- only single e-mail address On Fri, Nov 18, 2011 at 7:35 AM, Dilip Mishra // Viva < dilip.mis...@vivainfomedia.com> wrote: > Sorry for jumping in guys but I seem to face a similar problem where there > are domains which gets changed.
