All mails were transferred successfully. It took about 15 hours though, with a few torrents running "in the background", for a good measure 
So now I wonder if it would be a good idea to install spamassasin and configure it somehow clever to get rid of all this spam sitting on my bubba. I don't want just to delete the old no-spam mail as well, just the spam.
Do you think installing of spamassasin is a good idea or is it too heavy for bubba? Are the better, more lightweight alternatives? Ideally it should use internal and external filter (Bayesian, etc, with learning on + some external blacklist).
