Thanks for this...your regex expressions work well; how do I use wild
card regex's?
i.e I get many HELO's in the form:
c-24-9-152-139.client.comcast.net
adsl-69-212-19-224.dsl.milwwi.ameritech.net
Using * or ? As wilcards does not seem to work for me:-
I have lines such as:
\.client\.comcast\.net
\.dsl\.*\.ameritech\.net
Obviously I am doing something wrong...?
Help appreciated.
cheers
Scott

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).
