Hi

i've configured greylist on postfix 2.5.1 as described here
http://www.postfix.org/SMTPD_POLICY_README.html#greylist

The configuration works but i'm experiencing come problem with gmail,
infact gmail as a very large number of mailserver so each time when it
tries to deliver the mail the server has different ip and different
fqdn.

For example, i can see in the log:
