Ok, I didn't realize some systems might choose to go to the higher numbered MX records when a lower is available. Although spammers certainly make sense to pull that (I'm going thru the queue now, but so far much of it does appear to be spam with a few odds and ends of real email stuck in there). I guess my next step is to finally look into blacklists to cut down on some of this spam. I've not been using them as until this last month or so, spam really hasn't been a big problem for me. But its steadily getting worse, so its time I start fighting it actively. -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
