I thought the syntax for whitelisting RDNS via a file was to make a file with entries as follows:
.domain1.com
.domain2.com
.domain3.com
and that would whitelist anything ending in those. So it would
whitelist and machine whose name is mail1.domain1.com,
mail2.domain1.com as well as just domain1.com
However, either that's not working right or I have something else
configure incorrectly.
Can someone verify the whitelist file syntax? I looked through
the spamdyke documentation but I don't see any examples. All I see
is the syntax @domain1.com, but I thought that was only for the
files with senders and the like. E.g. a whitelist for email
address syntax.
Any help would be appreciated.
