I had a ISP all over me a couple of times, they claimed my system was sending numerous emails and that I needed to fix the problem. Blah blah blah...
I did everything, scanned for viruses, malware, adware, and found nothing. I then used their suggested scan program and found nothing.
The second time they came at me, I told them perhaps they needed to check their own $#@!&^( system for the problem because mine was behind a firewall, virus protection, scanned cleaned etc.
Never heard from them again, I guess they found their(their) problem!
