I would like to configure the SendNoAutoResponseRegExp option so that no Auto respons will be sent to a certain domain .

Can anyone help me with the right syntax for SendNoAutoResponseRegExp

(((MAILER-DAEMON|postmaster|abuse)@.+?\..+?)|.+?@mydomain\.nl)

and maybe explain a little about the standard syntax : <.+?\..+?'>

Sorry, no, that would be much too much. See (and read!) these comprehensive pages: man perl man perlrequick man perlretut man pcretest man pcrepattern http://perl.org/

And there is a bug in the “Forward” e-mail option. Is there already a fix available?

No, because there doesn't seem to be a bug in it. I guess you did (mis)configure too much. hth, Robert Kehl
