Greetings
My thanx to John Robinson & Ted Cooper for their input.
The suggestion my Ted was to add this rule to the rewrite section
but based on his suggestion I tried to use it in the ACL to generate a
deny but does not seem to have any effect :
deny authenticated = *
# condition = ${if !eq{$authenticated_id}{$sender_address}
{$authenticated_id}fail}
condition = ${if !eq{$authenticated_id}{$sender_address}fail}
message = Sender address and authentication address do not match
log_message = DENY : sender not equal authenticated_id
I have no idea what I am doing wrong here, the joy of being a noob (c:}
John suggested I try "control = submission"
(
http://exim.org/exim-html-current/doc/html/spec_html/ch44.html#SECTsubmodnon)
which seems to do what I want but not quite and again I have no idea
where to begin to fix it. It changes the
" From: "Michael L Griffin" <michael@???> "
to
" Sender: "info@??? "
where the info@??? is the $authenticated_id and the rest is the
host FQDN instead of what I am trying to achieve which is leaving the
GECO's ("Michael L Griffin") and changing only the $sender_address to
$authenticated_id
I figured out the add_header stuff finally; here for anyone else who
may want it( added to my rcpt acl) :
accept authenticated = *
add_header = X-AuthenticatedID: $authenticated_id
add_header = X-OriginalFromAdr: $sender_address
I am seriously out of my depth with teh rest and would appreciate
any assistance.
Regards
Michael
