All but a tiny fraction of mail coming into my network goes to Linux machines, and the few Windows machines all have up-to-date antivirus software on them, so I don't actually bother virus-scanning incoming mail. However, if you do decide that's among your needs, clamav is well regarded and integrates well with Postfix as a content filter. Your antispam options beyond Postfix are pretty thin on the ground: there's basically either SpamAssassin or DSpam. DSpam is capable of impressive performance (mine is currently running 99.511% overall accuracy), but is no longer maintained, has known unfixed bugs, and is difficult to set up properly. I would not recommend it for a new installation. So if you are going to use an antispam content filter, SpamAssassin is probably pretty much the only reasonable choice. > Is greylisting still something worth considering for general setups?

The number of people who swear by it is roughly comparable to the number who swear at people who use it. -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: 603.293.8485
