Correct, the problem originated when you replied to Werner's mail.
Werner's mail had the following header:
Mail-Followup-To: "Julian H. Stacey" <jhs at berklix.com>, gnupg-users at gnupg.org
The difference between that line and a simple Reply-to-All is that Werner would
be in the recipient list with the Reply-to-All, and not with the
Mail-Followup-To. Your reply should have only had gnupg-users at gnupg.org and your
manually added CC to Ulrich as recipients, since your MUA would conclude that
you don't need to CC yourself :).

Because Reply-To didn't really work out in practice for mailing lists, DJB came
up with two "non-canon" mail headers to remove ambiguity from the meaning of the
Reply-To header. He describes it in . Not everybody agrees with his
Whether you like the headers Bernstein created or not, it would seem Werner
didn't want to be on the recipient list, which is why I brought it up in my PS.

You can send me encrypted mail if you want some privacy.
