Have now passed 24 hours of being unable to reach IMAP and SMTP, both via SSL, at my hosting provider (dreamhost), from my home internet connection, Comcast XFinity.
At least the rep from Comcast was honest about not being able to help?
I called their “Comcast Security Assurance” line as Gemma suggested, but the guy I spoke to there didn’t understand the distinction between me trying to use Comcast IMAP service, which I’m not, and trying to reach MY IMAP service from their network. CSA forwarded me to the IMAP service team, 888-517-5296 and firstname.lastname@example.org, who passed the buck along to what seems like a general support line, 888-739-1379. I was on hold for twenty minutes at this one, followed by a ten-minute conversation which ended in the customer support rep telling me that Comcast Internet service does not allow/support connections on all services and ports. When I asked which specifically they DID allow, she said she would email me a list, and hung up on me.
