this is not similar, i think. The difference is that there is the comparision
CISTREQ(mx[n].host, localhost) so the localhost will not be discarded.
I didn't patch this file, but Thomas Knott wrote
that you need the localhost in the function deliver. I don't understand
this code very well, but it may help you to understand that we
can define a mailhost for every user in our own 'alias' db and that
our mailrelay has to decide where to forward incoming mails. Maybe
the final mailhost would send the mail back to the mailrelay.
