I'm Going To Go Postal

I always wondered where that phrase came from and now I know. All I'm trying to do is batch-forward, batch-bounce, batch-redirect (whichever term you prefer) emails from my accounts to my GMail account as my aber account is closing soon, and hosting provider has moved too. But I can't find any way of moving emails without them all being bundled into one big email (I want them as individual emails on my Gmail account) or without them being sent as attachments (which kind of defeats the purpose of moving them to my Gmail account in the first place).

I've even gone so far as to try Pine because I read an article on how to do exactly this with it, but it's now refusing to connect to the server and, after one of these little fits, the IMAP server refuses to let me connect from anywhere. What's infuriating is that it was working for about 5 minutes, and after a lot of blank emails being forwarded I did eventually coax it into forwarding the 4 emails in my inbox. But then it died and I can't even get it to display a list of folders, never mind anything else.

So I tried looking for an extension for Thunderbird thinking that somebody must have already had to do this, but the Mozilla website refused to let me even look at the extensions page because my version of Firefox is 1 minor revision behind the latest update. So I had to resort to looking at some other website that lists Thunderbird extensions which didn't feature any such forwarding extensions.

I've even tried Sylpheed, a GTK+ email client that I installed a few weeks ago when Thunderbird went mental on me, and while it has a handy "redirect" feature which appears to do exactly what I need, it doesn't work on more than one file at a time! The forward options are "inline" and "as attachment". As attachments is useless to me, and "inline" creates one bloody big email from all your existing email which is also no fucking use to me.

I'm seriously running out of ideas now. In fact, I'm on the brink of just writing a fucking Perl script to connect to a server, get each email from each folder in turn, and forward them to my Gmail account.
