Neither am I "an Exim expert". I am a Leaner too.
The main ACL's I use for ordinary incoming email are:-
acl_smtp_connect
I check the sender's IP address resolves to a hots name and then that
host name resolves to the IP address
acl_smtp_helo
I check the EHLO/HELO
acl_smtp_rcpt
I check the SMTP FROM and the SMTP RCPT
acl_smtp_data
I reject emails with no Message-ID: headers. This helps to remove junk
mail, sales circulars and other unwanted emails. I also reject if there
is no Subject: header but I accept a blank (or empty) Subject: header.
Good luck with your Exim adventure.
