Anyone knows why this Regexp, embedded in a text substitution with sg,
is not working (i.e. no replacement get's done)?
headers_add = "Subject: [$local_part] ${sg {this is a [test] for \
not having done so}{\N\[\w*\]\s\N}{}}"
having this line in exim4.conf returns the following subject:
[sysop] this is a [test] for not having done so
testing the pattern with pcretest works and even exim -be
works like charm.
[EMAIL PROTECTED]:~$ exim4 -be
> headers_add = "Subject: [$local_part] ${sg {this is a [test] for \
not having done so}{\N\[\w*\]\s\N}{}}"
headers_add = "Subject: [] this is a for not having done so"
what I'm trying to achieve is to remove any word-character used in
brackets and leave the rest of the subject intact. the string feeded to
sg is currently a test, if working I would use $h_subject: instead.
the whole config is needed for running a simplified mailinglist.
my config is exim 4.50 on debian sarge with a custom configfile
guided from the specs (see full listing below).
thanks in advanced for any hints, Marcel
