Mhonarc does this mangling.  I tried to stop it but couldn't find the
way.  I didn't investigate it too closely though, so most likely there
is a way to make it work.  If anyone wants to spend some time on it,
feel free to send patches.  Our resource files are here:

https://pgweb.postgresql.org/browser/trunk/archives/bin/resource-current
https://pgweb.postgresql.org/browser/trunk/archives/bin/resource-common
https://pgweb.postgresql.org/browser/trunk/archives/bin/resource-utf8

The actual mhonarc call is in this script:
https://pgweb.postgresql.org/browser/trunk/archives/bin/mk-mhonarc

The mhonarc documentation:
http://www.mhonarc.org/MHonArc/doc/mhonarc.html


Oh, FWIW, the Message-ID URLs (which are just hard links actually) are
created by this script:
https://pgweb.postgresql.org/browser/trunk/archives/bin/createmsgid.pl

It has a couple of holes (i.e. there are certain types of Message-Ids
for which it doesn't work), so patches are welcome too.
