Hello:

https://gitlab.gnome.org/GNOME/pan/-/issues/185

tl;dr: long Newsgroups: header fields are wrapped and encoded
incorrectly.

This has been a problem for a long time now.  Please advise.

Using commit cf43eb8929dc70e3fa89fead6bc948105019311a with a fresh
build.
Not sure if the encoding throws another wrench into things but I do know
that pan hands off the headers to ... looking it up again via ldd to see
what libs pan's loading... the gmime library... to do the header-
processing including header-folding, and that certain versions of gmime
were known to be buggy in this regard and do MIME-incompliant header
folding.
[...]
$ equery list -op gmime
  * Searching for gmime ...
[-P-] [  ] dev-libs/gmime-2.6.23-r2:2.6
[IP-] [  ] dev-libs/gmime-3.2.14:3.0

So you'll probably want gmime 3.2.13 from 2022 at least, if not 3.2.14,
introduced on Gentoo at least back in Sept (2023) and stabilized in April
(this year 2024).

If you have gmime 3.2.14 (and probably with 3.2.13 as I believe it was
after the known header-wrapping issues) the gmime header-wrapping bugs I
had seen should be fixed, as I'm guessing they were on 3.2.12 given the
timeline above. If you're upgraded beyond 3.2.12 then, the problem
probably /is/ the encoding, which as I said throws another wrench into
things that I'm not familiar with -- it could be pan itself or another
library responsible for that.

Thank you, Duncan!

I'm running Linux Mint 21.3, which is using gmime 3.2.7.  I will track down the latest version and link with that.

Thank you so much for the reply!
