http://www.DNSstuff.com/tools/ip4r.ch?ip=63.230.118.51 may provide a clue (FIVETENDUL, NJABL, ORBZIN, ORBZOUT, JIPPG-DUL, and a missing reverse DNS entry all count against you). >Reply message is: > Delivery failed 20 attempts: [EMAIL PROTECTED] This one is simply a problem reaching the msn.com mail servers -- that's not an uncommon occurrence. > ------Transcript of session follows ------- >[EMAIL PROTECTED] The >user's email name is not found. That's very similar to IMail's standard "I could not deliver the E-mail for some unknown reason; check the logs to see why" response you'll often get if other mailservers reject your mail because you are listed in spam databases. >These messages are coming from the recipients server.

Yes, you are definitely blacklisted (see the Spam Database Lookup at http://www.DNSstuff.com ). -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
