Deliver the mail out of the Postfix queue to a system that manages
such delayed email. When the mail is ready to go, re-submit it back
into Postfix. The system, can be an SMTP or LMTP server that queues
some mail, and possibly proxies other mail right back to Postfix
in real-time. With LMTP you can handle each recipient separately
if that is needed.
