I just had to change the password on my host email server. Now I can't send email and when I try, I her the error box asking me to enter a new password. I do that with the new pass word and the message comes back immediately. I checked my saved password for SMTP and it shows up as the new pass word. I can send mail from the host server email app so I know that end is working. I can also receive emails on Thunderbird from the host with the new password. I have 2 other email accounts on 3 different hosts and those send emails through Thunderbird without any issue. My host tech support checked out everything from their side and feel that it is something in Thunderbird. I have the newest version of Thunderbird which just downloaded a couple of days ago. I have checked everything I know but no luck. Help!
