And now for one of the reasons why I still get a lot of frozen messages
(see above):
In my exim (3.33) config I have:
# Verify sender of message
sender_verify
sender_verify_batch
# Reject it.
sender_verify_reject
# Allow invalid envelope if Sender:, Reply-To:, or From: is correct
sender_verify_fixup
# Also require correct From:, Sender: or Reply-To:
headers_sender_verify
headers_checks_fail
# Similar check for messages with NULL sender (in envelope)
headers_sender_verify_errmsg
According to rejectlog, this does stop some messages, but in many cases
the mail is still delivered even though I get an error message if I try to
send a reply (which I do a lot right now to test if my anti-spam measures
work.) Explanations?
Some example error messages:
