Hi list,
Exim 4.12, Openldap 2.1.10. Diligent use of spec.txt and FAQ.html with
Mozilla 1.1's search facility, which is o.k. Diligent searching in the
mail archives on my hard disk, coming up to 14 1/2 thousand postings of
all sorts since Exim v4 was released :-) I don't usually get stumped.
What I'm trying to do, is to reject mail from senders who claim to be a
local part in my domain. A certain (very small up to now, but growing)
amount of spam comes from these. Yes, I'm running SA 2.50 (latest CVS)
but don't filter small (< 2KB) messages.
I use the following ACL and it doesn't break anything, but telnetting in
from a machine in another domain [0] doesn't produce the wanted result.
Maybe it will with mail, I don't have that much experience yet.
The relevant part of acl_check_rcpt is:
______________________________________________________
begin acl
<acl stuff>
# Trying to shut out people from outside who say they're us.
# Works partly :-)
deny condition = ${if and { \
{!eq {$sender_address_domain}{$domain}} \
{eq {$sender_address_local_part}{*@$domain}} \
} \
{true}{false} \
}
<much more acl stuff>
_______________________________________________________
I notice that in the debug info the condition variables aren't expanded.
If I leave the $ sign out before "${if", they get expanded, but this
breaks the filter, which I'd expect. I have many more of this sort of
thing for ldap, AUTH etc.
Maybe I'm wasting my time. Anybody any ideas?
Best,
Tony
