Never had problem before, and not sure what happened. Today, I tried to send a phone pic via email, and came up with this error message on Notification Panel: "Unable to send mail." "The account setting is incorrect (Yahoo)." I press on the actual Notification, and it automatically prompts me to change account settings. Edit Account firstname.lastname@example.org Hit Next. Incoming Settings Protocol > IMAP Email address > email@example.com Password > ******* IMAP server > android.imap.mail.yahoo.com Security type > SSL Server Port > 993 Above is my current settings, but I did not change anything. I re-entered my yahoo password to see if that's problem, and now get a warning message saying, "Authentication failed. Please verify username/password" but that's my correct username and password for Yahoo. Any idea how I can fix? Thanks!
