prevent/stop email spam SmarterMail/windows 2003???
We have a few reseller clients complaining about the huge amount of spam coming through even though they have setup all of their accounts with the built-in spam filtering in SmarterMail. And our resellers are getting complains from their clients who they have catchall accounts set too and they (resellers) are going to provide their clients some virus/spam/spyware protection softwares as well to help them reduce the spam.
We only have a ClamAv running on the server.
So are there any software (like SpamAssassin) that we can install on the server or if there is anything else that can be done on the server to help reduce the amount of spam?
