Like many others, my IP 220.127.116.11 (burnersystems.com) is listed in bl.spamcop.net Causes of listing * System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop) * SpamCop users have reported system as a source of spam less than 10 times in the past week I have checked for open relays, and found none. You are welcome to confirm this. Our firewall is only allowing SMTP traffic outbound on port 25 from our mail server. I have scanned our Exchange server with Symantec, and we have mail filtering for exchange. Nothing was found. Can somebody help me please? This has just started this monday.
