This may seem strange for this forum, but I actually outsourced the virus/spam filtering to an external provider. They have my MX records, and I have SMTP locked down to only accept email from them.
Yes it is expensive, but so is my bandwidth. I calculated that my internet connection was using between 64K and 256K (depending on the time of day) just to through away known spam from blacklists. Lots of spam was still getting through to the user, so I was killing my bandwidth, and still getting user complaints. If you can afford it, it may be easier. ======================================================================= -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Holm Sent: Wednesday, May 18, 2005 7:16 AM To: [email protected] Subject: [courier-users] What is the best user-based anti-spam solution? Hi, beeing lost in the zillions of posibilities maybe you could give me advice in setting up the "best" antispam solution with courier-mta? What is best for me? User-based automatically generated whitelists would be a nice feature, a webinterface for users would be nice. I really like the idea of blocking spam via the BLACKLISTS environment variable, but how to implement a whitelist of ips that should never be blocked?
