On my (bullseye) system, that field is what is used to get my full
name.
It's what I'd expect to be used, unless configured otherwise.
(Note that I don't personally send mail this way—I use mutt, of course.)
I don't intend to send mail from this machine myself, I want mail from
the system (e.g. unattended-upgrades) delivered to my personal mailbox.
No, my system uses mailutils:
As you may have seen in my response to Greg, replacing mailutils with
bsd-mailx (and adding a configuration line) did solve the issue. I think
this at least proves that nullmailer did not mess with the From header.
I don't know why your mailutils works when mine doesn't. Perhaps a
difference between the bookworm and bullseye versions, perhaps a
configuration setting somewhere. I gave up; I've spent way more time on
this than I should already. The mail will all be sent to me; it's
ultimately irrelevant what name is in the header. It was just an itch.
(I did learn a few things along the way, though, so it wasn't a waste of
time!)
I don't know much/anything about nullmailer, or why you chose it.
(But then, the only reason I use exim4 is because I know how to
# dpkg-reconfigure exim4-config
it.)
I used to use exim4, and I have instructions written down for
configuring it. But exim4 is a full-fledged mail server, and I don't
need that (or feel competent to maintain it), so I went looking for
something more lightweight. Nullmailer seemed adequate for my needs.
Thanks, kind regards,
Gertjan.
