%description
    Postgrey is a Postfix MTA policy server implementing Greylisting.
    Related to whitelists and blacklists, a greylist indicates those
    emails (originating from unknown IPs) which are rejected with a
    "try again later" message. The email in question will be delayed
    until the sending MTA tries again, but this is where spam loses
    out. Most spam is not sent out using RFC compliant MTAs, and so
    the spamming software will not "try again later".
