I'm looking for a hosted spam filter service along the lines of Postini. (If you've worked in IT, you know the kind of service I mean - you point the MX record for mail.company.com to the spam filter, and then log into the spam filter's web-based admin console and have it deliver mail to the business's internal mail server.)
However, what I want is the admin (me) to have the following capabilities:
- Block mail senders by IP or IP range
- Be able to manually sort messages into "spam" or "not-spam" categories for Bayesian filtering (even if I have to log into a web-based console to do it).
I can easily set up an internally
hosted SpamAssassin box to do both of these things and more, but that means (1) I have an extra box on-site, which is what I'm trying to avoid and (2) spam gets pulled down via the on-site broadband, cutting into the bandwidth available to users.
I can find services that offer IP blocking (though not all of them do) but none that give me any control at all over the Bayesian filters.
Does anybody have any recommendations?
every person who doesn't like an acquired taste always seems to think everyone who likes it is faking it. it should be an official fallacy.
the "no true scotch man" fallacy.
