Hi Odhiambo,
For Exim4U's exim.conf,� it should go in acl_check_content which
runs immedately after the smtp session's data submission.� We've
got facilities for blacklisting IP addresses and I don't see a
problem with adding blacklisting for sender addresses and
domains.� Here is another example:

Let me know if you have specific ideas on how you think this
should be implemented.
Thanks,
Gordon
