Hello:
Just wondering if you resolved this issue? And if so how?
I have the same hack on my Plesk server, started in Jan/Feb this year - a vendor trying to send me an email noticed that Gmail was blocking email being directed to my Gmail account, the hacker scripts had been sending out 10's...
Credit the designer of the new Plesk GUI and features...
Wow --- must have been the same pro who designed the forum registration with hoop after hoop after hoop...
Unfortunately, we cannot wait for the next version for an old faithful feature to be added - after no matter how many people...
