What are your opinions on pcre vs regexp for header_, body_, and mime_checks in Postfix?
I looked at the regexp_table and prce_table man pages, and see almost no difference other than the available flags.

The main difference is that pcre uses the same regular expression syntax as perl and python. I consider this an advantage as I've been using this syntax for the better part of 20 years, and don't have to remember how other systems handle REs (which is a major part of my reason for starting to use perl in the late '80s).

It's been a while since I've used the setup, but I've always used pcre since it is the same regex as perl. More familiarity and, at the time I used it, more documentation (at least readily available).
YMMV.

whenever you can, use pcre. it has a "better" syntax. it's also faster but since you shouldn't abuse header_checks, this is not important.
