I've been reading the documentation, and I've so far failed to come up
with a solution to the following problem:
I want, in index or pager view, to be able to send the current
message's message-id and folder to a Perl script. I'm happy to extract
the message-id from the Perl script - and I can see how I'd send just
the email to the script, but the inclusion of the mailbox it's in is
providing a sticking point. Any sensible comments?
