I've used TB for many years, absolutely great! I added a 4th email address to my accounts. (this one from Yahoo) I can receive all mails but started having problems sending mails in TB since I added a yahoo email address. The yahoo address can send and receive therefore I believe a conflict developed with the SMTP settings. Does TB support two SMTPs ? How can I solve this challenging situation? I send emails to myself to test each one. I tried to set the old SMTP to use the same port as yahoo but no success. (well mixed.. I didn't receive it but when I went on email providers web-mail I could see it was there but it didn't come to TB. I tried turning off firewall. I have the old SMTP as default.

I tried to let TB auto configure my email addresses by adding them as a new email account,  These settings were more associated with my old ISP. but still do not work. Please help. The only email that seems to be working 100% is the latest Yahoo addition.  so what of my previous three wit a different domain?

Chosen solution

Thank you Zenos. I had a good think about being able to get emails and send them from webmail. Therefore it was a TB settings problem, not just SMTP it was incoming settings also. Something had changed them.

         I found the solution. I realised that having added a new email address or perhaps the latest update caused the difficulty. 
  • What steps I took; after juggling about with in & out settings changing default. changing Ports and back. I tried to send emails again and again. after closing and reopening TB. TB looked for my password to one email after the other , when I put in my passwords.. hey presto all was back to normal.

So therefore my conclusion is that something hidden had altered or forced an ignore of my passwords. even though in the security window all appeared normal, it was not. (hidden change)

       My changing settings forced TB to ask for password again, and a positive result...

For those who have similar problems , just go straight to security tab/ passwords_ reveal. then copy them in word, not to loose them. Then delete all passwords, close TB and restart then it should request passwords and option to remember them also. I recommend to try this before we pull our hair out ;-) If that fails then copy all in and out settings to word and manually install settings again , restart TB and everything should go well. ( P.S. verify from your ISP what the correct settings and ports are , good luck!!

Thunderbird supports one active smtp per incoming account. Under each account's Settings, you can see which smtp server account is associated with it, and change it as necessary.

Each account you add via the new account wizard, Thunderbird should either seek a new custom smtp set-up, or offer you an existing one. For services such as yahoo, gmail, hotmail/live mail/outlook.com, it's generally necessary to use the one they provide. Email services provided by your ISP or some organization such as webhosts may depend on your ISP or email provider offering a "general purpose" smtp server.

To add an smtp "account", go to Tools|Account Settings and at the end of the list, "Outgoing Server (SMTP)" allows you to add new ones.

A common cause of distress is experienced by users who switch between a direct internet connection and a VPN, and need a different SMTP for each environment, and this is an area that doesn't work smoothly in Thunderbird. But I don't think this is your problem.

I do think yopu may have a separate issue with incoming email. If you can see it in the webmail portal but not in Thunderbird, then it would seems that the final delivery from server to Thunderbird has failed. By this point, I'd think it has gone well past SMTP.
