    Issue is most likely either with your ISP or Yahoo, you should first be in touch with your ISP and if they can't help then  Yahoo support. Also double check to see your Mail's settings are correct, on rare occasion they can become corrupt so you need to re-enter them even though they look OK.

    Typical reply but your system probably is not the cause. Here is the link to trouble shooting, please go through it carefully.

    I have been having this problem on our home computers with AT&T/Yahoo for several weeks and finally gave up and got a gmail account in order to send mail. I spent several hours with a very nice lady in Apple Support, but she could not solve the problem, either.  I tried everything I could think of, even resetting the Time Capsule and modem.  When I reset the modem, it threw me off line, so I  had to call AT&T support.  She got me back on line, but was no help in getting my outgoing mail working.  When I received a survey asking how the service was, I'm afraid I was not very complimentary.  This morning I had a call from a very nice service person who had read my complaints and had a solution for me--I can now send mail on my account.


    He had me shut off Airport (I was not using it anyway).  Then I deleted my email account (in Mail Preferences) and started over with it (-/+).  If you have stuff in your Inbox you don't want to lose, create a temporary mailbox and copy to it. Then go to System Preferences>Network>Advanced>DNS>+ and add whatever DNS address numbers your provider uses.  The DNS Servers for AT&T/Yahoo he gave me were: and  That solved my problem.  If you're using a machine on a wireless network, you will have to turn Airport back on at some point in order to reconnect to the internet.  You will have to do this for each computer on your network. When you reconnect to the server, it will re-download everything on there, so you may want to clean it off first (I had over 1000 on mine for the last week).


    Hope this works for you!
