Yep, that's what happened -- but when I either precede the 'require
verify = header_sender' by 'accept hosts = 127.0.0.1' or else replace
it by 'require verify = sender' the message is accepted and has a
'From: postmaster@???' header.

Ah, I understand that now. But, as noted, the From: header is present, and
moreover, these FormMail generated messages are sent only to addresses
at domain.com which is a local domain.

There is a From: header, although there is no To: header -- just an
Envelope-to: header.

It had no effect. I'm using exim-4.41-140.
