You might have DKIM and SPF in SpamAssassin; but these are totally 
useless unless the domain you are having this problem with (e.g. 
123l.com) actually publishes or uses them...

smf at smf-laptop:~$ host -t TXT 123l.com
123l.com has no TXT record

Same with smf-spf or milter-spiff; they'll only fix this problem if a 
policy is published for the domain in question (ideally a '-all' hard fail).
