Hi, The SMTP version is 6.06. & the relay setting is set to 'No Mail Relay'. So how this sender gets authentication?
We do have rdeliver entries in logs, but to get rid of the problem we have setup mail.hanmail.net on our own IMail. This atleast drops the mails there and avoids the excessive CPU usage and exploitation of SMTP.
