I have the solution, but first here's the problem:
I have two gmail accounts (call them A&B) and 2 yahoo accounts (Call them C&D) that have had no problem sending mail or getting replies to the correct email until about a week ago. The problem(s) that occurred recently are: I send an email from gmail user A, but when it get's to its destination the receiver sees the email address for B to reply to. Likewise for Yahoo, I send from C and recipient gets D's email address instead.
After scouring similar issues, all archived now, I tried their solutions. All did not work. Here's some details learned though:
Sending email uses definitions for a SMTP server. Until recently, I had no problems with email addresses being interchanged by Thunderbird, but as per some of the archives solutions I reviewed my SMTP definitions and noticed I did NOT have unique SMPT definitions for each email address! But now, this is a problem! So, how do you define unique SMTP definitions. Simply (right!) open ACCOUNT Settings and Edit the SMTP specifying unique addresses on the Outgoing Server. I was instructed to EDIT the SMTP Outgoing Server where I received a screen with a "Description" field and a "User Name" field. Instructions were to change the "User Name" by adding the account email address in front. Other solutions were to change the "Description Field" to the account email address. I tried each and both. What happens today is that when you change one of these for one email type, e.g., gmail, all the other gmail accounts change automatically to that newly modified change you made. In other words, ALL gmail accounts get changed to the new modification, So, I you change A, B will also change to the same information; likewise if you change B, A will duplicate it. Same with Yahoo accounts: change C and D also gets the change or D and C gets the change. There was no way around this behavior to make them unique.
SOLUTION: So, instead, I REMOVED one of the accounts, say account A and ADDED it back. NOW both A & B were unique. Same with the Yahoo C & D accounts after removing C and adding back. Problem after testing was resolved.
May I add that even worse problems occurred before the remove and add if you have told Windows 10 to default to Thunderbird as the email handler and you clicked on a Website's correspondence dialog to send an email. Then it NEVER sent the email to the expected recipient (Website owner) and instead sent it FROM either A or B, TO wither A or B, C to either A or B! I have retried this function since my solution change, so can't claim full victory yet. But, the removal and addition of an account back now supplies a unique SMTP automatically from Thunderbird.
Hope this helps you if you have the problems described.
