Suppose you have an email account and a shell account on a Unix server. Furthermore, suppose that you yourself use a laptop and download your mail from the server by POP3 or IMAP, and send it via SMTP using the server as a smarthost. Now imagine that for some reason ( your dynamic IP, or your geographic location ) SMTP access is denied. What can you do?

I've got an account on a FreeBSD machine on which I've got 12 years' worth of email, and a beautiful spamassassin / procmail setup. All my friends know the account ( let's call it 'utumno@smarthost.com' and the server 'smarthost.com' ) so I'd really hate having to change it. I use fetchmail/procmail combo to download mail through IMAP, and sylpheed-claws-gtk2 to read it.

However, now I am working overseas, and recently smarthost.com decided to deny all SMTP relay ( including SMTP AUTH ) from abroad.
