So, mh talks SMTP on a pipe to exim, which is a rather unusual method
of delivering e-mail.

Are you positive that it is exim inserting the Sender:-Header?

Try: swaks --pipe 'exim -bs' --from <your address> --to <other address>

and see whether the generated message has a Sender header. If it
doesn't, then you need to yell at mh, not at exim.

Running a mail server is rocket science, you cannot get along without
reading docs.

Upgrading from sarge to etch (sic!) generally does not require
headaches from the exim side.

as far as I know, the default was not changed. I cannot reproduce your
issue here.
