Great, simple article, how would the masquerading work if I’m using Apache virtual hosts ie more than 1 domain on the server. If a php app from one virtual host sends mail using the PHP mail() function how do I set which from address is used?

Thanks

Hi nixcraft,

No I haven’t set this up. To be fully honest, I am not familiar with virtual unix user name mapping. Can you explain a little bit more.

I did try to use the virtusertable file but it didn’t to work for outgoing email. The problem I am trying to solve is EXACTLY the on you mention in your post: I have a machine (prod1) and a user (prod) and I want to send emails as invitation@.com (I am just interested in outgoing email… and no, I am not a spammer :-)

The masquerade works for the domain name, but for the user, I ended up having to create a unix user ‘invitation’ on my box and sudo to invitation before sending the emails… It works fine but I am sure there is a better/simpler way…

Thanks for your reply btw.

Do you have virtual UNIX user name mapping like:
user1@domain.com drealuser

???

Nice. So, this explains how to ‘hide’ the domain name. But what about the user name ? With the changes you describe, it still shows our real unix username. Am I missing something here ?

thanks for your help.
