I get the following error message when trying to send an email as of this morning.


"An error occurred while sending mail. The mail server responded: 5.1.0 Authentication required. Please verify that your email address is correct in your account"

I have my outgoing server configures as it says it the help menu when using comcast

Error=No Authentication

Your setting - Authentication method = No Authentication

Should be normal password.

What are you using for SMTP settings? It sounds like they are not right.

Description: Comcast Server Name: smtp.comcast.net port: 465 User Name: <not specified> Authentication method: No authentication connection security: SSL/TLS

Thank you, it did fix it, I don't know why or how it got changed, it worked fine yesterday.

The link I posted above shows to have it set to "No Authentication" ????

Thanks again.

Unfortunately everything you read on the Internet is not true.

This is from Comcast page.

   Incoming Mail Server Name: imap.comcast.net
   Incoming Mail Server Port Number:
       Recommended: 993 with SSL ON
       Only if Needed: 143 with SSL ON
   Outgoing Mail Server Name: smtp.comcast.net
   Outgoing Mail Server Port Number:
       Recommended: 587 (SMTP)
       Only if Needed: 465 (SMTPS)
   SSL Encryption: checked
   Authentication: XFINITY username and password required

The provider configures their servers and should have the most up to date info. I happen to use Comcast so i know what they are looking for. Keep in mind that Thunderbird is a volunteer operation and some documentations is slow to be updated.
