Thunderbird - sending only first name as email id?
Why was this happening? How long had I been making an idiot of myself?
It turns out that I wasn't. My Account Settings in Thunderbird were unchanged, and the email was indeed going out with my full name.
But when the copy came in, Thunderbird was looking up my own email address in my Address Book, finding an entry which was marked simply "John" and using that ID in the "From" column. There is a setting "Always prefer display name over message header" which you can disable.
