    Hello All,

    I am trying to tighten up my security so that I don’t have an open relay for spam, i have configured the Virtual SMTP Server so that only people who authenticate or are from the specified list can forward email.

    Is there anything else that I can do?

    Do any of you suggest good software to block this? Maybe freeware… or what about spam prevention software? I’m interested in hearing suggestions..
