I read this, but I don't understand where is the difference wether \n is
expanded by exim to a newline (without using \N or using \\n) or using
\N so PCRE transforms \n to a newline.

Thanks, this works. But it only works, because I know the exact format
of $spam_report. How can I tell ${sg{}} to include \n to the matching
characters of .*? I think in Perl this was done by the modifier /s.

Is there any way on exim (besides to embed Perl) to extract a value like

$id = $1 if $spam_report =~ /(^|\n)X-purgate-ID: (.*?)(\n|$)/s ?

Kind regards
