Why has it to be a single regex implementing all the logic?

You could simply match /From: (.*?) <(.*?)>/ and than check $1 and $2 with Perl

Far better maintainable.

Unless ... this isn't really a Perl question?

  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
