What spam-fighting features to you offer?
We offer SpamAssassin, which can be enabled for your account in Cpanel. SpamAssassin tags each email with a spam rating which your email program can use to filter out spam.We also offer SpamBox which will collect emails that you designate the server to consider spam (like those over a certain SpamAssassin rating), which you can clear it out periodically.
If you still get too much spam, we recommend filtering your email through Spamcop.net. They provide a good filter system at a good price.
