I am unable to receive e-mail.  It keeps asking for a username and password but won't accept it.  I get this error message:

Unable to send or receive messages for the Twcny.rr (twomutts) account. An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.
