Greetings!
I'm looking into a method to strip off very large mime attachments on 
outbound email, and store it locally on a HTTP / FTP server, and send a 
link out to it in the email. The recipient can then download the file 
via the web, and not clog the SMTP stream.

I've seen this done on some milter programs, but nothing yet for 
MailScanner.  Has anyone done any development work on this? A quick 
check of the archives didn't yield much.

I think we could develop something off of the Maximum Attachment Size, 
with a rule set, and perhaps an external perl or shell script to handle 
the mime storage, and link replacement.

Thoughts?
