SpamEater 4.1.0.185 beta

Description by the Software Developer:
"Once you tell SpamEater Pro where your ISP's mail server is, and your login information, SpamEater will connect with the server, either on a timed basis, or manually as you desire, and check the messages on the server for spam, removing any found and, optionally, archiving locally.

There are a number of fully configurable checks that are performed on the messages. These range from checks to see if the message is from one of your defined Approved Senders, a blocked sender, from a blocked country code, checking to see if the server that delivered the message is in one of any number of internet blacklist databases, server authorization checks with SPF (NEW!), to a virtually unlimited number of powerful filter rules that we provide and update for you - and you can create your own too.

If a message is determined to be spam, or fails any of the defined checks, it can be silently deleted from the server, bounced back to the sender (NEW in v4), archived locally and deleted from the server, and/or easy cut-n-paste to SpamCop web forms for complaint generation to the sender's and advertiser's ISPs - you decide!"
