Why do e-mails sent to OS X 10.6.x Snow Leopard Server arrive only after a delay?
Snow Leopard Server implements an anti-spam technique called Greylisting. While this is quite effective, it has the side effect of causing delays during mail delivery.
If you wish to turn it off, you can disable anti-spam measures in Server Admin. To specifically only stop Greylisting do the following:
smtpd_recipient_restrictions = permit_sasl_authenticated permit_mynetworks reje ct_unauth_destination check_policy_service unix:private/policy permit
smtpd_recipient_restrictions = permit_sasl_authenticated permit_mynetworks reje ct_unauth_destination permit
When done, issue:
sudo postfix reload
