Hello to all!

I've implemented a postfix server with greylist service.
I would install the greylist service on another server and so postfix will ask about greylist with inet to the second server.
In this way I'll introdice two or three postfix servers (MX) that will query the same greylist server and maintain a single greylist DB.

The configuration should be like this:

smtpd_recipient_restrictions =
reject_rbl_client bl.blacklist.cbl,
reject_unauth_destination,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
check_policy_service inet:<2.serverIP>:60000,
permit

I've tested what happen when if the service on the greylist server stops. I obtain:

451 4.3.5 Server configuration problem

Is there a way to accept mails even if the greylist service is stopped?
How can I set up a query timeout and accept the mail session if the greylist service is not responding?

Thank's to all!

Simon
