Hi,
on one of our SSD Servers, there was some Spam sending Problem last Week ago.
The Client had some Viruses on PC and Spammer logged in with Password on that Client Mailbox.
After we changed the Password, this Botnet permanently ran against this Mailbox and after 36 hours it looked like he stopped with attack.
But today i saw it just got a little slower and we now nearly have 5k IP Adresses arround the World who trying to access that one Mailbox.
Does anyone has any Tipp what we can...
