Not a problem ... I can also set it so that there are various levels of
'checks' ... for instance, all I'm using right now is ?all, which is a softfail
vs an absolute one ... apparently this lets the email through to something like
Spamassassin, who can then use it for scoring purposes (if I understand it
correctly) ...

neutral: The SPF record specifies explicitly that nothing can be said about
         validity
softfail: The SPF record has designated the host as NOT being allowed to send
but
          is in transition
fail: The SPF record has designated the host as NOT being allowed to send

Now, personally, I'm not 100% certain what use 'neutral' is, but, again, if I'm
reading things right ...

If I do something like:

a mx ?all

what it says is that all email that comes either from the IP of
mail.postgresql.org, or its listed MX servers will pass, no questions asked ...
?all will pass, but in such a way that something like spamassassin scores
differently then if it did come from 'a / mx' ...

As I said at the top though, I'm not in a big rush, just want to do it as it
should help, as Tom mentions, keep the spam down somewhat ...
