sort mail with qmail

[Eric Poubeau]

 My problem:
 
 I have a small server, and I dont want sent too big mail,
 so I want to sort e-mail BEFORE sending, catch too big mail,
 grep and convert attachements, re-sent mail with just a pointer to
 attachement and text/plain.
 
 How I can do?

 Thanks in advance
