I have enabled the mail and IMAP ofcourse to receive the emails and then blocked the outgoing ports 25,465,587,2525 so no mail can be sent even after this I am facing mail spam attacks and abuse reports especially UCE Listings.
Can someone please help me regarding it? I have checked all settings and they seem correct but still facing the issue. What could be the problem?
