I want to extract the first part of an email address from the

Example pseudo code:
my ($first_part) = $email_file =~ /^Deliver-To: (.*)/;
body __LOCAL_AWKWARD_INTRO /hi $first_part/i
How can I do this in my .cf file?
With a silly kludge, a full rule that matches the complete raw email
with a
single regex. Example in stock rules:
full __FROM_NAME_IN_MSG
/^From:\s+([^<]\S+\s\S+)\s(?=.{1,2048}^\1\r?$)/sm
So something like (untested)
full __LOCAL_AWKWARD_INTRO
/^Delivered-To:\s+<([^@>]+)(?=.{1,2048}\bHi\s+\1\b)/sm
Thanks. I don't quite understand the {1,2048} bit. That looks like a
look ahead assertion up to 2048 characters? What is magical about 2048?
What if the "Delivered-To" header is more than 2048 characters away from
the salutation, which doesn't seem unlikely.
