For about 24 hours I have been receiving the following error message when sending emails....

There was a problem!
Not sure why, but our usually-reliable server goofed-up while sending this message. Please try again.

I received a "help" answer from Yahoo, but the recommendations to fix the problem didn't work. The email said to reply to the email if it did not work. But I can't email!!! Has anyone else had this error message? What did you do to fix it?

Forgot to mention...

My husband and son each have Yahoo accounts and they are not having any problems sending emails off of this computer. I also tried my computer at work and get the same error.
