Re: Comcast blocked port 25 (SMTP)???

I've found that port 25 is always blocked on Comcast residential accounts - only on the business accounts is it allowed... in which case, perhaps the letter is in error?

It's not blocked by default:

Disagree ! I've known many people that are Comcast subs and also have read many posts on various forums and I've never seen a pattern or any evidence to indicate/prove your assertion. I have been a CC residential subscriber for nine years myself and port 25 always was and still is open and active here..

I've tested from my sister's Comcast connection in Oregon, from time to time, and never found their connection to have a port 25 block. Per their own policy, Comcast only blocks port 25 out on a case-by-case basis.
