[Update on that: A fifth route that I thought of later also passes the
mail without corruption.]

It's the non-printable character in Heiko Ei.feldt's name that
provokes the corruption.  In the original, that "." was an octet with
hexadecimal code 0xdf.

I determined this by sending mails with and without that one character
through the other of the routes that corrupted it.  And the content of
the mail received through that other route exactly matches the content
of the mail received on this mailing list, so I'm confident that the
same thing is causing the corruption in both cases.

And on the other route that "same thing" betrays itself with the
following header:

   X-MIME-Autoconverted: from 8bit to quoted-printable by nahkohe.jetcafe.org id p5KJijsw064717

This header appears in mail received through the other route, but not
in the mail from SGVLUG.  Nor does it appear in mail through the other
route that does not contain the unprintable character.

The "other route", in case you're curious, is via jetcafe.org, where I
still have a mail address left over from when they were my ISP.

Is it necessary or appropriate for the SGVLUG mailing list software to
corrupt mail this way?  If so, it might be further appropriate to
include an "X-MIME-Autoconverted:" header.
