Call PHP script in Postfix

Personally, I'd suggest a cron + imap (passive) solution, ie. your script check the email via imap every X seconds or minutes, then acts upon it if new are found.

Why? Scales better, you can move to different config/mailserver/cluster with NO code changes (just imap connection params, if even that), plus you have better control over incoming and possibly outgoing messages that way, and such standardized code is then available for future use in different conditions.

Thanks Azathoth, was never too keen on the IMAP/Cron method as the script needed activated immediately although I found a solution on this forum (I should have searched properly before posting) http://www.linode.com/forums/viewtopic.php?p=28034

Basically, I created forward in my database which forwards an email address to a local user account, then setup the aliases file to point the local account to the PHP script, works perfectly.

I second the IMAP suggestion, specially if the PHP implementation supports IDLE. You can leave the script running and it will get notification when a new message arrives.

To answer you original question, I got mine to work by first adding an alias from the virtual domain to a local user: example@virtualdomain.com -> localuser (no domain on this one), and then adding the localuser to the /etc/aliases file. I should mention I don't use the MySQL backend, just flat files.

Hope that makes sense, let me know otherwise.

edit2: Heh, and now I realize you figured it out from a reply I had given someone else here. I had forgotten about that. Good times.

Haha, nice one, thanks.
