I can't send email. I keep getting a pop : Yahoo'up that tells me "Some errors occured while processing the required tasks. Please review....for details..."The host 'Yahoo' could not be found. Please verify that you entered the server name correctly. Account: 'yahoo' server

<I moved this to the Email section where it will be found and answered quicker>

Check your settings and try again.
INcoming: POP.yahoo.com
OUTgoing: SMTP.yahoo.com

Are you using a utility that allows a local email client to access Yahoo? Try accessing your Yahoo account from the standard Yahoo Mail website.

Can you send mail while logging into mail at Yahoo? It sounds like you are trying to use a POP3 client to send your mail, but you have to pay for POP3 service from Yahoo.
