[Mimedefang] Requeue failed messages

[Joseph Brennan]

The first thing that I wonder about is how you will determine the recipient 
to deliver to.  Sendmail -t will parse the To and Cc headers but they need 
not correspond to the recipient.  I think the recipient can be parsed from 
the COMMANDS file if you save that.

But the same question arises for the Squirrelmail access too, so maybe you 
have sorted the mail by recipient as it comes in.  In that case if you know 
the recipient, something like

sendmail user at host.tld < messagefile

might be what you want.  That won't set the sender address unless you do 
some more work to extract it from Return-Path and feed that on command line 
too.

I've never attempted this type of mail manipulation so I can only offer 
first thoughts. I wonder whether ANYONE else has tried your method!
