fetchmail and imap help

[Andrej Marjan]

On a general note, why not just copy the spool file locally and then inject
it locally? Why spin up an IMAP server just to, in effect, copy
/var/spool/mail/neil locally and then run procmail on it?

Probably doesn't matter but you have two listen settings there.

It seems like there are a ton of automation steps in there without
intermediate testing. Do all the constituent parts work individually? For
instance, if you ssh into the remote host by hand, forwarding port 1143, and
then run dovecot by hand, does that work with fetchmail? How about other
IMAP clients?
