Update - the dictionary attack worked something like this... Some clod would set up a system to email, in rapid sequence, nonsense like
aardvark@swedesdomain.com
abacus@swedesdomain.com
....
zygote@swedesdomain.com
The rapid flow of B.S. spiked the CPU and bandwidth. I actually volunteered to shut down my POP mail server for as long as it took for the attacks to cease. My host said they'd do this. The attack terminated, yet my email still works, so I'm not sure exactly what happened.
I'll cross my fingers and hope. |
