Q:

How do I clear spam e-mails to fake addresses on my domain?

I was just looking around cPanel and noticed that the default mail account is taking up over a gigabyte of storage.  I opened it up in webmail and saw there are over 200,000 spam e-mails sent to randomly generated e-mails like name@mydomain.com.  I am unable to delete them because the webmail installed on cPanel can't handle such a large number of e-mails and won't load the inbox.  How do I clear out these e-mails?
If it matters, I am running CentOS 5.5 on a dedicated box, but I'd rather not have to delete from the command line if at all possible.

A:

This appears to be a backscatter attack.
