Comcast as smart Host smtp.comcast.net
Up until this Wednesday, outbound eMail was going through with no problem. Wednesday was my Comcast "upgrade of speed" cutover. Now all outbound eMails are "delayed and then posted as non-deliverable.
Talking with Comcast techie, he said smtp port 25 is being blocked on a rollout by Comcast.
I recycled the cable modem & router first.
I then re-ran smart host wizard and complete credentials and setup. However, the wizard does not have port setting.
Am I in a port issue? if so, how do I change to SSL port 465?
THX, I have no outbound eMail now. Inbound delivery is fine.
