This all started when I cancelled Xfinity and went to Frontier Internet. I had previously used Thunderbird for 8 years through Xfinity with no problems. I have contacted Xfinity and Frontier and both have told me it is a problem with a Thunderbird setting.

Sending of the message failed. An error occured while sending mail: Outgoing mail server (smtp) error. The server responded: resomta-c2p-555920.sys.comcast.net resonta-c2p-555920 sys.comcast.net. Excesive failed authentication. ESMTP server temporarily not available.
