Hi all, This is my setup: ISP Modem - Router - SBS 2003. Problem: IP was blacklisted due to large ammount of Spam sent. I used the following article : https://support.microsoft.com/kb/886208 , cleaned the machines using Malware Bytes. However when i restart the SMTP Service, it restarts sending SPAM ( Few Postmaster@*mydomain*.com and mostly the sender is "Best Entertainment" sent with varied email addresses). When i untick Anonymous Access in the Default Smtp Virtual Server the spamming sops.So I eventually left it for a while so that at least the users could send emails without the mail server sending spam, obviously as a temp fix, so not to get blacklisted.

Your advice is highly appreciated.

Thanks .
