At first I thought nothing of it, as that server is kind of hinky at best. Happened to mention the return to hubby and he said his email #'s were way down from usual, and that he tried emailing himself just to check. He uses Outlook Express to poll for email but can go to the web2web page to check for mail. The test mail he sent to himself showed in the 'sent' folder of OLE, but never arrived. He went to the web page, and nothing was there. I called our ISP techs, they checked everything out with me, even sent email to him email addy, ( tech used same @ as my email) and it arrived without problem. I sent email from my account again, they 'saw' it being sent, but it didn't arrive, instead it was returned with the same above error.
I used his myanything or whatever it is called server support board, got back an email that said using our ISP as the outgoing (SMTP) was incorrect, and to change the port as well. Of course that didn't work. Changed it all back. Some mail comes in, test emails from me to him error back to me, test to him from his puter never arrive anywhere.
I let him restore back one week, just in case one of the windows updates we both had done last week was the cause. ONE test email came thru (his email to his email) but after that nada.
Now to make things a bit more confusing, I answered a question on another forum that uses email to respond. It was returned to me with the same exact error as posted above (different email name, of course, but same error)
I have no clue where to go from here
