Can't send Yahoo mail using Mail app
So, I'm used to every now and then getting the verify password or unable to connect message for my Yahoo account in Mail. However, I've been getting it for the past week or so now. It downloads messages without any problem, but refuses to send any out. I've deleted teh account multiple times and added it back, no change. I can send messages just fine from the Yahoo site, as well as my iPhone without any trouble.
This is getting very frustrating. I'm lettign Mail set up the account on it's own each time I tried to re-add it. I've also followed the settings on the Yahoo help page - neither works.
Anyone else having this issue too?
MacBook Pro, OS X Mavericks (10.9.1)
