  1. I think I found it -- some old user accounts on Imail had apparently been compromised. Thanks for your help!
  2. Thanks for getting back to me. I'm running a virus scan on the server now, but is there any more information you can give me? Maybe a header of the spam that was sent so I can see the User Agent of the server or something? I'm trying to figure out if this is a problem in my Imail or in my IIS SMTP. Thanks, -av
  3. My own email server keeps getting blocked: Diagnostic-Code: smtp;554 Service unavailable; Client host [] blocked using bl.spamcop.net; Blocked - see http://www.spamcop.net/bl.shtml? A few weeks ago, when it first got blocked, I had a bunch of vacation autoresponders and stuff like that. I've since disabled all of that, and turned off pretty much every bounce message I can find (I'm using IMail v8). But I keep getting listed. The same server also runs a forum where registration emails are sent to whatever address people put in, so there's really nothing I can do if someone puts in a spamcop "honeypot" address. Do you have any suggestions? Thanks -av
