It is not a bad time.  I just won't be able to apply it right away, but
people (like Pierre) who are interested in send-email enhancement can help
improving your patch by reviewing.

You have this piece of code

to pick up the "To: " addressees.  If your user deletes Cc: line, would
that regexp still capture them in @tmp_to?  How?

Ah, somehow I thought C2 you are writing into (message.final) was used as
the final payload, but you are right.  The foreach () loop at the toplevel
reads them and interprets them.

So you were trying to handle folded headers after all, I see.

But if you were to go that route, I think you are much better off doing so
by enabling the header folding for all the header lines in the while (<C>)
loop that currently reads one line at a time.

I however hove to wonder why we are not using any canned e-mail header
parser for this part of the code.  Surely there must be a widely used one
that everybody who writes Perl uses???
