Ok,
I switched form comcast and have used Thunderbird for years. I switched the comcast accounts over to my new Verizon accounts. Everything looks correct but on the sub accounts and only the sub accounts, if I try to send an email I get the following message
"an error occurred while sending mail. The mail server responded: 5.7.1 Authentication is required to send mail as {edited for privacy}@verizon.net>, Please verify that your email address is correct in your mail preferences and try again"
soooo.... What did I do wrong and who is {edited for privacy}@verizon.net???
I hate to delete all the accounts and try from scratch since I still have read email from my old account that I don't want to lose.
Thanks in advance!
John
