My config snippet:
# define macro to refer in ACL
REJECTHELO=/etc/exim/acls/helorejectrcpt
And, in appropriate place at RCPT ACL:
deny condition = ${lookup {$sender_helo_name}nwildlsearch{REJECTHELO}{yes}{no}}
hosts = ! +relay_from_hosts
message = Mail is blocked: ${lookup {$sender_helo_name}nwildlsearch{REJECTHELO}{$value}}
My REJECTHELO file contains entries like:
^\d+-\d+-\d+
^ip[0-9a-f]{8}\.speed\.planet\.nl
^h\d+n\d+fls\d+o\d+\.telia\.com
^dialup-
^user\d{1,3}\.net\d{2,3}
and so on (with corresponding message in each line, naturally).
