[opensuse] How to force default outgoing Thunderbird mail account

I have multiple email accounts that I read in Thunderbird using its unified inbox feature. I am working to gradually eliminate a couple of accounts, and would like to force my replies to emails received in my old accounts to be sent using my new preferred account. I know how to set the default outgoing account in Thunderbird for new messages. Is there a way to force the use of a specific outgoing mail account when replying to messages received on different accounts?
