BlackMamba is a semi-automatic spam filter and
email previewer. It lets you connect to your POP3
mail server and peek into your mailbox.
BlackMamba automatically categorizes the messages
as "friendly", "possible spam", and "spam" based
on a few simple configuration steps. It allows you
to delete the messages, and it maintains an
address book, a list of spammers, and a mail size
filter. It should be useful if you've gone on a
holiday and haven't checked your email for weeks
and know that your mailbox will be full of junk.
BlackMamba sorts your email messages without
downloading the messages in their entirety.
