This all started when I cancelled Xfinity Internet 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.
This is the error message I receive..........
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. Excessive failed authentication. ESMTP server temporarily not available.
I have since cancelled Thunderbird and removed the program from my laptop but still have it on my Desktop computer. I am still receiving the same error message on my desktop. Everything is the same setting it has been for eight years. The only change I made was cancelling my Xfinity TV, Internet and mobile phone service. I still have Xfinity email.
