[IMail Forum] Why my server is relaying for hanmail.net???

[[EMAIL PROTECTED]]

Hi All,   We are using IMail 6.05 on Win 2K.  The relay settings are set to 'No Mail Relay'.   Since last few months the server is trying to relay the mails to [EMAIL PROTECTED] or [EMAIL PROTECTED] While delivering such mails the SMTP process eats up 100% CPU.  Even if we delete the mail from queue along with the msd file in queue it doesn't release the CPU.  We have to restart the server to get back to the normal. The strange this is the sender's ID is any random ID e.g. [EMAIL PROTECTED].   The actions taken to avoid this: 1.  Edit the Kill File and put the sender's ID or the domain to kill the mails..:  But here the problem is with the recipient ID [EMAIL PROTECTED] 2.  We made a use of IMail delivery pattern.  We setup the domains mail.hanmail.net and mail.daum.net on our IMail.  This atleast doesn't hang up the SMTP process.. and put the service down.   But last week the server accepted the mails delivery from [EMAIL PROTECTED].. Where 216.187.93.106 is our server's IP.  But we have not setup any such server in IMail...  This user was just spamming through our server.   Why the server is acceptong such mails when the sender's IDs are invalid and the mail relay setting setup to 'No Mail Relay'.. We have confirmed that the mails are not generated locally on the server but accepted from the mail clients that are connecting to the server.  Is anything wrong with the server settings?  Anybody else faces this problem?   Do let me know...   Regards, Aparna
