postfix mapping issues
 

Im trying to map my email address to avoid people trying to log into my server with the same email prefix. For example, my username is JoeSmith but I would like my email address to be jsmith@domain.com. Easy enough, but it only works on inbound email.... so jsmith@domain.com gets mapped correctly to the joesmith account, but when joe smith sends out an email address, it appears like joesmith@domain.com which completly defeats the purpose.

My setup is:
Postfix-Procmail-Fetchmail-SpamAssassin-squirrelmail-Courier IMAP

Any suggestions would be greatly appreciated
Thank you,

What you want to do is to make use of address rewriting. You should read http://www.postfix.org/rewrite.html

I think thats more for domains and not so much for outbound usernames

You can rewrite user@domain.com to otheruser@domain.com.
Isn't that what you are looking for ?

Hi,

Can you describe your postfix setup a bit. Like how are you changing your address in the first place. Are you using canonical_maps. If so... try reversing the process by using virtual_alias_maps.

Hope this helps
