Is anyone suddenly having Mail problems connecting to Yahoo servers?

Question

I run two Intel iMacs on my home network.  Both run Snow Leopard.  On my machine that runs 10.6.8, I recently installed several Safari updates. Currently Safari is at Version 5.1.5 (6534.55.3), my wife's iMac Safari is Version 5.1.4.  I began having problems downloading email from the Yahoo server (I have ATT UVerse broadband service).  Internet access seems solid but I started getting constant requests to enter my password for the Yahoo server.  ATT and the alleged Yahoo tech support have been unable and unwilling to help beyond reading the usual scripts.
My wife's iMac is able to send and receive emails using the Apple Mail client, I can only receive emails using Mail, sending results in an endlessly spinning wheel in the "sent" mailbox.  I have carefully examined the Mail Preferences on my wife's iMac and verified that they are duplicated on mine. For some reason, my Mail cannot send to the Yahoo SMPT server.
Any suggestions to this somewhat convoluted question?

Answer 1

I see that you are both having the same issues as myslef. I think I may have a solution for your problem. In your mail accounts section (Mail > Preferences > Accounts) rechange the settings to as follows:
IMAP (Incoming Mail Server) information:
Server name: imap.mail.me.com
SSL Required: Yes
Port: 993
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
SMTP (outgoing mail server) information:
Server name: smtp.mail.me.com
SSL Required: Yes
Port: 587
SMTP Authentication Required: Yes
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
Hope this helps!
