Using multiple SMTP servers in Thunderbird

I have two different mail accounts which I use within one Thunderbird environment on my Windows 10 computer. However, I am finding more and more that emails go to the recipient's spam folder (or are rejected) because the domain of the SMTP server does not match that of the mail (on one of the two accounts). I don't want to keep changing the SMTP server depending on which mail account I send from.

I don't want to use a different program per mail account, and I don't want to just use one account as I segregate between mails to people I know well and more general mail, also to keep spam in one account.

Is there any way to solve this?

You can specify the SMTP server for an account at the bottom of the account settings page. That is why it is important to fill in the description on the SMTP settings page so you can be sure you're assigning the proper SMTP server.

More detail may help. Generally, there should be one SMTP server for each account. Providing server info for incoming and outgoing for both accounts may prove useful.

In Thunderbird "Account Settings" there is a section per account. The server settings there are the incoming server settings, e.g .the POP Mail Server, log on details and frequency to check for new mails. Then at the bottom of the list there is "Outgoing Server (SMTP)" and this is only one entry. I can create multiple SMTP server settings, of which one is favourite, but that applies to all accounts. I cannot link one account to one SMTP server.

Yes, you can. in 'account settings' pane, scroll down left side to 'Outgoing servers SMTP' and that lists the servers. Each needs a unique description so you will be able to be sure you're linking proper account to each server. An SMTP server should be used by only one account.

Thank you for your response. I had already created 2 outgoing servers, with a relevant description. But as far as I can see, I have to go to these settings and check / change the "default" whenever I send a mail. I cannot link a specific mail address to a specific SMTP server so that the selection is automatic. Is that correct?

Thank you very much. I had not noticed that before. So easy to do, once you know how.
