What you want to do is set a 'true' condition for
bypass_spam_checks
for one of your domains (and include subdomains). 0 is false
and 1 is
true. When the read_hash function reads the file in question
it looks
for a left hand side and a right hand side. If the right
hand side is
missing is assumes a 1 (true). The entry .domain.nl includes
domain.nl
so it would be sufficient to simply place this in the file:
.domain.nl
which is equivalent to:
.domain.nl 1
The explicit zero you place here:
bypass_spam_checks_maps =
(read_hash("$MYHOME/spam_domains"), 0);
is fine but it is not required, so this could be:
bypass_spam_checks_maps =
(read_hash("$MYHOME/spam_domains"), );
and in this case it would work the same. It works because
only the
domain(s) listed in the file will be bypassed. Any other
domain will
simply not be found, and therefore will not be bypassed.
In situations where you are bypassing scanning for some
recipients and
not others it is a good idea to also place those recipients
that are
bypassing in the corresponding lovers maps. This is a good
idea because
when a message is addressed to multiple recipients, those
recipients may
disagree on whether scanning should occur or not. Bypassing
saves time
and energy but does not guarantee delivery in the same
manner being in
a lovers map would.
