Finally when I created a new Gmail IMAP account in SeaMonkey, it worked! Then I manually set up a with all the proper setting. My solution was first to remove the Gmail account I had set up and also the passwords that were associated with it. That's why I kept getting the Yahoo pop up. So when I tried to set up the gmail account, it accepted mt settings for POP or IMAP (I had tried both), but did not ask for SMTP settings and automatically used the settings. My SeaMonkey application already had two Yahoo accounts with a server. But in SeaMonkey the settings have to be done manually. In Thunderbird, once you enter a gmail address, it automatically sets the IMAP and SMTP settings. So I ticked that off.Ģ) I learned how Thunderbird and SeaMonkey set up accounts differently. I finally solved my problems (more than one).ġ) I eventually discovered in the Gmail account settings that POP was enabled but IMAP was not. I want to keep using Thunderbird on my PC and not have to go to GMail website to use it.ĭear sfhowes, thanks for all your help.

I have used Thunderbird successfully for years. I need this new account for a volunteer position that I have. I followed the YouTube video on how to add your Gmail account to Thunderbird that appears on Mozilla Support. One help website recommended >Port 587, OAuth2, STARTTLS> but that did not work either. When I look at the STMP settings, they are all identical with the one that works except for the new email address.

I already have another Gmail account in Thunderbird that has always worked just fine. In Thunderbird, the email account is created automatically in SeaMonkey, I created it manually. I have tried everything - removing account and re-creating the account several times. Outgoing mail does not arrive in destination inbox. In Thunderbird and SeaMonkey, only the Incoming mail works. I have added a new Gmail account in Thunderbird (also did it in SeaMonkey and BlueMail).
