Unable to send email from iPhone or ipad, Unable to send email from iPhone or ipad

Question

Recently, I have become unable to send emails from my comcast email account.  I tried uninstalling and reinstalling the account, but get an error (Cannot send. Username or password for Comcast invalid).  The username and password are correct, though, as my email works fine on my non-Mac laptop. Any suggestions?

Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.
