I saw this happen to another mail server
ages ago ( not Imail ) . The server was actually compromised via HTTP and the
email was been generated via HTTP and just passed from one local machine to the
next. It even spoofed the IP and host names to make things really difficult. I
cant say that’s your problem, but when looking for an answer you some
times need to look further than your mail server, it could just be the delivery
agent. Best Regards Matt Brown Managing Director, Head Geek Data Sanctuary Internet Backup & B

[mailto:[EMAIL PROTECTED] On
Behalf Of [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 |
