I've searched the WIKI and found the solution to what I am trying to do... It's
Q0710. It fits perfectly however the solution doesn't seem to work. I seem to
keep coming up with errors with the "condition" portion of my acl. Since I'm
very new to doing ACL's, can someone tell me if this ACL is correct and
possibly help me get mine working? I'll copy it here:
Q0710
Question
I want to reject certain sender-recipient combinations, with a specific message
for each such combination.
Answer
Set up a file (or database) containing the messages, keyed by the combination,
for example: send...@sdomain1=>recipie...@rdomain1: blocked because...
send...@sdomain2=>recipie...@rdomain2: blocked because...If
you have lots of recipients for the same sender, it might be easier to
generate this file from more convenient data. In your ACL that is run
for each RCPT command, you can then put: deny message =
${lookup{$sender_address=>$local_p...@$domain}\
lsearch{/that/file}}
condition = ${lookup{$sender_address=>$local_p...@$domain}\
lsearch{/that/file}}{yes}{no}}The
condition is tested first. If the lookup succeeds, the condition
succeeds so access is denied. The message is then expanded, but the
lookup won't be repeated, because Exim will have cached the previous
result. This approach blocks
only incoming SMTP messages. If you need to do similar blocks for
messages that do not arrive over SMTP, you have to set up a suitable redirect
router with a :fail: setting.
