[exim] mail-from exception to rbl

i can't imagine no one has been here before, so thought i would
ask.

i run mail-abuse.org dnsrbl in acl_check_rcpt:. turns out, of
course, that there are a few critical senders living behind qil
blocked smtp senders. so i want to accept a few mail-from
before the dnsrbl rejects. so i have hacked the brutal

accept local_parts = (user1\@\do\.main|foo\@\earthlink\.\com)

do i have this correctly? is there something cleaner i should
do?
