"By perl style regular expressions" I was referring to PCRE. Yes, Perl
does variable interpolation before running the regex, but then Exim
does string expansion before running the regex as well.
I'm not sure what you're getting at. Do you think there was a bug in
the suggestion I made of using:
${if match {$h_X-UoP-Loop:}{^\\Q$sender_address \\E}}
Because in the above, $sender_address is first expanded to the real
email address, and then any pattern meta-chars in that email address
are treated as normal chars...
Looks good to me.
