I’ve been using Thunderbird for email for years, typically every day. All of a sudden after a typical first step to download email, usually done every day, I can’t send an email, as I normally have every day. What’s the problem indicated by the following pop up message that is received and how do I correct it? “ Login to account “Verizon Online” failed. Login to server smtp.verizon.net with username Thomas.arlo failed. Retry; Enter New Password; Cancel”
