As you say in your second post, emacs is treating $) as a special
variable, instead of treating the $ as part of the regex.  I know
I've seen it documented somewhere that emacs uses a fairly simple
rule for interpreting $ characters in perl-mode; in most places
it just "escapes" the next character.  ("$/" must be an exception.)

The best way to fix your problem, I think, is just to move the $
outside of the parentheses:

            if ($zeile =~ /^Subject:(.*?)$/) {

That should have the same effect in perl, since the $ end marker
wasn't contributing anything to the value of $1 after the match.
