Thunderbird 52.6.0 (Ubuntu, Mac OS X) does not pick up any address when replying to an email with both a From and a Reply to addresses.
I have tried this on several versions of Ubuntu and on several versions of Mac OS X and the problem is the same. It appears that this is a bug that was previously fixed and that has reappeared.

This is not happening with a mailing list. To compound the problem, the function works with some received emails and not others. I have added images of the pertinent part of the source for the sent email and the response pane generated by Thunderbird.
I use no Add-ons. I have tried both of your suggestions in any case. Neither solved the problem. I really appreciate your thinking about this.
The sending address is one that I control but not one that is known to, or accessed by, Thunderbird. I will try a totally different address. Notice, though, that in my pictures the Reply-to address is not only ignored, so is the From address. No address is filled in. I will keep experimenting. This may simply be a bug that is very unusual and will be very hard to cure. Thanks very much again for all the time you have devoted!
