I inherited admin duties of a postfix server despite having no postfix experience. It's running a service called sqlgrey that is causing all emails from google.com to be greylisted for 30 minutes. I have added *.google.com to /etc/sqlgrey/clients_fqdn_whitelist.local but I am not sure how to force sqlgrey to reload its whitelist. The documentation shows how to kill sqlgrey and how to start it as a daemon, but I don't know if that is safe or whether sqlgrey needs to be started as a specific user, etc. Any ideas?
