That's RFC822 header verification, so an ACL (DATA ACL?) has:
verify = header_sender
That's documented in section 38.12 of The Exim Specification; the
item from spec.txt is:
-----------------------------< cut here >-------------------------------
verify = header_sender/<options>
This condition is relevant only in an ACL that is run after a message has
been received, that is, in an ACL specified by "acl_smtp_data". It checks
that there is a verifiable sender address in at least one of the Sender:,
Reply-To:, or From: header lines. Details of address verification and the
options are given later, starting at section 38.20. You can combine this
condition with the "senders" condition to restrict it to bounce messages
only:
deny senders = :
message = A valid sender header is required for bounces
!verify = header_sender

Your Exim Config thing is turning on sender-in-message-header
verification, not (just?) SMTP Envelope Sender verification.

Pass, sorry. But the should be enough to look more closely at what your
FormMail setup is doing wrong in missing out the relevant headers.
I don't know if Exim applies its fix-up logic for adding a Sender:
header before or after this ACL is run, but you might look to see if
that config tool lets you specify "unless it's locally submitted".
