I use Thunderbird (52.4.0). Occasionally, after sending an email to someone, I want to add more to that email before they reply. To do this, I simply go to my Sent emails, click on appropriate email and click Reply. This always used to automatically put in the To box the address I desire. These days it puts my own email address in there. (On the one hand, this makes sense: I sent the email, so 'reply' shoudl go to the sender.) Let me give an example.
Suppose my email address is
sam@t.comand I want to emailjohn@d.com. I've sentJohnan email, say, at 12pm. At 1pm, before he has replied, I want to add some more information. I go toSent, and click on the email I sent him. I then clickReply. In theTobox, it sayssam@t.com; in the past, it would've saidjohn@d.com.
As noted above, I'm not saying that this doesn't make sense from a purely abstract point of view. However, it's incredibly unhelpful. I often find myself accidentally emailing myself. (When I had Outlook, it did the same; sometimes I wouldn't even notice that I'd email myself, and the person I wanted to contact never knew anything about it.)
My question is this: how can I (or, is there a way that I can) change it so that it's back to how it used to be?
