Check your secure logs:
#more /var/log/secure
Look for *lots* of connections, verifying the IP address will give you
anything obvious; i.e. Taiwanese IP logging-in.
Check the webspace for the user for any Phisting scams & web back doors.
Check the rest of the box has not been compromised...

Cheers,
Charles

Having an issue with an old enemy on a new BO box.

net.tw,
gov.tw
org.tw
net.tw
com.tw

take your pick.

Some how, they must know one of the emails userid and password on the
box and are sending 4000 - 5000 spams per hour into my mail queue.

I have turned off PopBeforeSMTP, so probably not sending email out.
Probably.

How do I tell which account is being used to connect.

Any other suggestion of course is always appreciated.

Steve
