As I was reading again, just now, through the various online documents
and man pages relating to filtering, I realized that there exists a
rather fundamental anomaly, either with the docs or (more likely) with
my understanding.
This page:
http://www.postfix.org/SMTPD_ACCESS_README.html
says that evaluation stops when a result of PERMIT, REJECT or DEFER is
produced. However this page:
http://www.postfix.org/access.5.html
mentions REJECT, DEFER, "OK", and also a number of other possible table
lookup results that are not mentioned in the SMTPD_ACCESS_README document.
Is "OK" functionally equlvalent to "PERMIT"?
In my own local lookup tables, I have mostly been using "PERMIT". Is
that either more correct or, alternatively, less correct than using "OK"?
Is a table lookup result of, say, "550 Bugger Off!" equivalent, in
practice (as regards to continuation of restriction processing) to the
keyword "REJECT", as it is described in the SMTPD_ACCESS_README document?
(My apologies if these are all FAQs, but the discrepancies between the
two documents mentioned above do make things a wee bit confusing.)
