Skip the box B part. Pull an e-mail from IMAP mailbox A, filter it,
then either discard it or append it to IMAP mailbox C (with A and C
possibly on different servers).

Right. Nothing's local except the filtering.

If I'm going to use the SMTP server on box C, then I don't think
there's a need for the intermediate maildir stop, since I can have
procmail pipe the message to something like msmtp to deliver it to the
SMTP server. There are a couple problem with using the SMTP server.
The first is that you can't specify a mailbox. The big problem is
that the SMTP server may rewrite headers. For example, if it's gmail's
SMTP server, it will always muck up the From: header so the message
appars to be from the account that was used to log in to the SMTP
server (you loose the original From: header). Using the IMAP server
allows you to store a message an any folder you want and the headers
are unchanged.

I think it would be simpler to write an LDA that delivers a message to
an IMAP mailbox and have procmail pipe messages to that for delivery.
It should only take a couple dozen lines of Python... (famous last words)
