So the thing to check with the author of postfwd2 is what's going on
with the regular expression on line 1168.
That is a scary one. It seems like an attempt to express all of the
leniencies in a config format in a single regex, where a preliminary
canonicalization (reducing all runs of whitespace to a single space
maybe?) would eliminate the need for some of the complexities.
postfwd takes regular expressions from a user's configuration file.
These expressions were malformed (starting from line 230 in the config
file).
But yes, that's really an issue to take up with the author and/or
other postfwd2 users. The postfwd.org site indicates that a user
mailing list exists.
Yep, that's the right place for it. Sorry, for the "noise" :)
