I think it's something to do with "." not matching \n. In perl, you can
use the /s modifier, so perhaps

if $header_Received: matches "(?s)from blah.example.com.*by mail.example.net" then

would do the right thing, since I think Exim uses Perl compatible REs,
and including (?s) in a RE is the same as using the /s modifier on the
end. (See perlre(1) manpage.)

disclaimer: I may well be talking bullshit.
