spammers seem to remember old IPs for a long time, so rehoming your mail server can reduce spam. putting in a deliberately broken backup MX with big number can also screw them up - spammers often inject email into the non-primary MXers because sometimes that sometimes avoids spam being rejected. SPF and other techniques aren't actually that effective, or effective for long IMHO; in fact Postini found that spammers adopted SPF before regular users! lots of useful strategies, but this isn't really the place to deal with it. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
