Just sharing a little code that some might find useful. This is a way to
store a list of regular expressions in a file to select a host. What
this does it read a text file and build a regex that looks like:
^.*\.(line1|line2|line3)$
This can be modified and used for anything where you are testing
something against a list.
warn message = X-Big-Host: $sender_host_name
condition = ${if match {$sender_host_name}\
{^.*\.\x28${sg{${sg{${sg{${readfile{/etc/exim/acllists/bighosts.txt}{|}}}{\\|+}{|}}}{#.*?\\|}{}}}{\\|\$}{}}\x29\$}{yes}{no}}
List looks like this:
locos\.com
aol\.com
yahoo\..*
