 %description
     Postgrey is a Postfix MTA policy server implementing Greylisting.
-    Greylisting is related to Whitelisting and Blacklisting. What
-    happen is that each time a given mailbox receives an email from
-    an unknown contact (ip), that mail is rejected with a "try again
-    later"-message. This, in the short run, means that all mail gets
-    delayed atleast until the sender tries again - but this is where
-    spam looses out! Most spam is not sent out using RFC compliant MTAs;
-    the spamming software will not try again later.
+    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".
