Re: Comcast decides to block port 25 IN and OUT with no notice.

said by biomesh:

I don't see how running smtp tests from a residential connection are truly valid tests. What if the SMTP server had its own firewall or blacklist enabled for some of comcast's ip ranges. You should really be doing these tests from a datacenter level connection.

One who is testing against such an SMTP server for legitimate reasons would be aware of those potential problems.
