I get absurd amounts of spam. One week away from my emai, gives me 40.000 messages of SPAM. I recently discoverd SpamTrap, and it chews nicely through all that spam.
The problem is just that if the spamtrap-folder is specified, all those 40.000 spam-messages are stuffed into this IMAP-folder.
I would like to suggest that there would be some kind of counter that would create a new file after eg. 10.000 messages in that folder (like spamtrap.001, spamtrap.002 etc)
