Re: Dynamic Host Filters

[john@xxxxxxxxxxxxxxx (John Sievert)]

You need a * after the domain name too - like *somedomain.com* or
alternatively, *somedomain*  then the NOT.  I have had problems when I
didn't have the trailing star.

Actually, I am not sure this logic is right.  Because of the OR then any
item being true will satisfy the logic so anytime it is not somedomain.com
it will be true.  You don't get to use parenthesis in these filters to
specify hierarchy.  What you would want would be

relays.ordb.org        OR
bl.spamcop.net             OR
relays.osirusoft.com    AND
*somedomain.com             NOT

I don't do it this way, and I am not sure of the precedence.   This presumes
that the Ors are calculated first and then anded with the NOT.  If this is
the precedence it will work.  If not, you will need to go to separate
filters.

 I have separate filters set up for each of my blackholes so that I can see
which are trapping what email - helps in responding to those rejected in
telling them what blackhole doesn't like them.  The other reason I have
separate filters for blackholes is that they are very hard to test unless
you have a known and listed open relay handy.

Why isn't 'phonetic' spelled the way it sounds?
