I've used outgoing.yahoo.verizon.net port 25 for years and now all of a sudden it doesn't work.
I've tried all the other ports and tried a port scan. Port 25 is open for outgoing.verizon.net but there are NO ports open for outgoing.yahoo.verizon.net.
There has got to be a problem with this server but there's nothing posted and tech support seems clueless.
Any one?
