I received the following from Verizon. I do use Outlook to POP my Yahoo and VZ email, however when I make the change to the Yahoo mail I get error messages. Has anyone else been affected by this?
Email Program Users (Outlook®, Thunderbird, Mac Mail, etc)
If you use a non-Verizon account such as Gmail, Hotmail, Yahoo or AOL to send your emails through a program like Outlook®, Thunderbird or MacMail, you will need to make a simple change to your 'Server Port Number' setting in your email account - change the 'Server Port 25' setting to 'Server Port 587' setting.
