With today's CPU speeds, we're talking about nanoseconds to scan an Email.
If, for the odd event, the Email is exessively huge, then just include the
first 20, 30, 50... or whatever... number of lines. You're saving the
original in the queue anyways, so you don't need to worry about chopping up
the confirmation Email. Make it a point of putting the confirmation at the
top of the body of the Email and that'll help as well.

This can be resolved by putting the confirmation code on its own line and
making it short. This avoids word wrapping. Quoting and everything else
should be a non-issue because you do a sub-string search that throws
everything out until it comes to the correct sub-string (ie - "conf'#") ,
then reads the next 'x' number of characters.

Comparing the "FROM" line on a confirmed Email with the the one in the queue
should eliminate this.

Agreed! Any other issues you can think of?
