In addition to having a failure on the SMTP, I noticed that the machines
admin email was somehow changed, I updated it back to mine and since then, I
have received over 3,000 "Postmaster Notify -- Mail Delivery Subsystem"
failures.
Additionally, I have received over 100 "Port Scan Detected", but
surprisingly, the IP that shows as scanning is my DNS server [Yes, my DNS is
separate from the Cobalt 550 Machine].
Due to these problems, I have shut off my SMTP and POP server options on the
machine.
Any suggestions or solutions to resolve this matter and get the SMTP back
online?
