How can one disable the default Reply-To address when Thunderbird sends to a specific domain?
Context
When I send new mail from my destination (.*@PM\.me) address, having a default Reply-To set, as file://$HOME/.thunderbird/l96s5pce.default-esr/prefs.js#:~:text=user_pref("mail.identity.id1.reply_to", "[email protected]");, is useful, so that recipients respond to my desired alias, rather than my destination address. It's somewhat like a security fallback.
However, when responding to messages sent to an alias, that static, default Reply-To address can be problematic, because it overrides otherwise-inherit Reply-To that $alias_local_part+$recipient_local_part=$recipient_domain_part@rokejulianlockhart.addy.io provides. [1]
The Question
Consequently, how can I enter a default Reply-To address, for when I send mail, but not have Thunderbird automatically apply it when I respond/send to mail from a specific domain?
