Broadband: Comcast shuts down email account for alleged spamming?

Comcast shuts down email account for alleged spamming?

Have had Comcast Internet access for about 8 months. No recent changes in my operating profile/activities.

Got a email on July 4th stating Comcast had detected suspicious activity from my email account - so Comcast disabled port 25. Comcast gave me no warning, they just made this change. I was instructed to define another port for sending / receiving emails.

I am surprised/ disappointed that Comcast would change my account without first contacting me. I occasionally send/receive emails with video clips (about 3 MB) in size. And on average, send/receive about 50 emails per day. Comcast said this matched the profile of a spammer. That I could have a virus on my computer that is doing illegal activity.

I know Comcast monitors downloads, especially for movies, and will slow down your access speed. And for repeat offenders, even end their service contract. But I had not heard that Comcast was monitoring email activity.

I use the McAfee software Comcast provides to have security and do a weekly virus scan. What Comcast has told me to do to reset my computer has not worked. Spent 3 hours today with their HelpDesk and I'm still unable to use my machine. Never had a problem BEFORE Comcast disable port 25.

Comcast now wants "full access to my computer - to fix my problem". I did not have any problems BEFORE Comcast touched things so I do not think I should trust them.

BUT has anyone else heard of ISPs disabling email accounts like this?
