Sendmail with individual user account
 
Aim: Save attachments to server storage.
 
1. Setup sendmail account to forward to PHP script.
 
In the home directory (/home/user) on the foo.bar machine make 
and edit a file called ".forward". In this file put in the 
following.
 
|"/dir_to_php_script/process.php"
 
This will forward any email sent to user@foo.bar.com to the 
php script.
 
2. PHP script to process email "/dir_to_php_script/process.php"
[Don't forget to chmod 755 process.php]
