Don, There could be a few possibilities depending on circumstances. Is it the same PC/laptop being used? That can narrow it down. I've heard of times where an ISP detects too many junk/infected emails being sent from their server using another ISP's email address that they might blacklist the offending ISP's emails until the junk/infected emails are under control. That is something you would have to ask RoadRunner about. One way to get around that would be to use the webmail (web interface) instead of Outlook.

At home in Florida using Brighthouse/RoadRunner internet service email works great. User is now on vacation in Bakersville, North Carolina and using Frontier (formerly Verizon) DSL service. At vacation home outbound messages do not send, but in town (Spruce Pine, NC) at internet café (AT&T Internet Service, I think) mail sends OK. At Bakersville library using unknown service, but probably either Frontier or AT&T via government network, email also sends OK. Any idea why email sends OK everywhere except from the vacation home?
