I am running Vista and Windows Mail. I have the same problem as DonATX. I get the same error message too.
I had my SMTP port set to 465 and POP3 port set to 995 and I had both SSL boxes checked. Until yesterday, these settings worked for me for over a year. Then yesterday, I could not send email and I would onlt receive email 1 out of 10 tries of clicking the Send/Receive button.
My kids computer is running XP and they can send email with the above setting.
I called AT&T tech support and spent close to an hour on the phone. The tech support guy was able to see my screen and operate my computer after I ran an application for remote access found on the AT&T Yahoo web page. He played around with the settings and could not get it to work. Until, he unmarked the check boxes for SSL. When he did that, Windows Mail woudl change the port POP3 to 110 and SMTP to 25. When he clicked on Send/Receive, the email in my outbox was sent and I was receiving email again.
By the way, during this whole time, I had my antivirus software, Avira, turned off.
These settings are not secure and I got an automaticlly generate email from AT&T Yahoo staing that I am not using the secure port and SSL settings.
Bottom line: I can get and send email when I use the default port settings with SSL not checked. I cannot send email with the AT&T secure settings. My kids XP computer can send and receive email with the AT&T secure settings.
This all started happening to me just yesterday. Did Microsoft send out an update to Windows Mail that has a bug in it?
