[pmg-devel] [PATCH v2 pmg-docs 1/2] close #2449: clarify DNSBL check in SMTP Whitelist

[Mira Limbeck]

Rename 'RBL' to 'DNSBL' to be consistent with the option under Mail
Proxy -> Options. This should get rid of the confusion between the
checks spamassassin does (RBL in our config) and the checks postscreen
does (DNSBL in our config).

+DNSBL checks are done by `postscreen` which works on IP addresses and networks.

 NOTE: If you use a backup MX server (e.g. your ISP offers this service
 for you) you should always add those servers here.
