Are The Spammers Getting Smarter?
I modified my spam filtering software for the mail server running on this machine to try to reduce the load. Previously it ran after email was accepted and queued for the users. Now it runs when the initial connection is made to the mail server using Spamassassin’s milter1 called spamass-milter. I made the change so that, in theory, spam wouldn’t run through the virus filter creating unnecessary work for the antivirus program. Spamass-milter rejects mail when it reaches a certain level of spaminess and it never gets to the users. This works fairly well, there are over 2000 rejected emails from last week alone and as of this morning there are almost 200 rejected. The problem is that spammers seem to have adapted (again) somewhat to the rejects. I am still seeing close to 200/day that slip in. And that’s just my email – which includes the “catchall” address. I guess I should just take comfort in the fact that more is rejected than accepted.
1 – a “milter” is a mail filter.
