They simply arrive late.
It might, depending on the receiving software. My system shows this: X-Greylist: IP, sender and recipient auto-whitelisted, not delayed by milter-greylist-1.6 (mx.example.org [10.0.0.1]); Mon, 14 Jul 2014 21:57:46 -0400 (EDT) > > These are the top two headers from a delayed message.

Twenty minutes seems > a long time for greylisting. Why? My host will continue to refuse mail for 15 minutes before autowhitelisting, but most mail gets delayed for 2-4 hours depending on the retry cycle of the sending machine (the host doesn't get a lot of mail from most sites). > You would have to look at the mail logs from the NUWVICMS2 machine > to see what it was doing from 08:50 until 09:11 (GMT+1000) to know > why the mail was delayed.

This should also appear in the NUWVICMS2 machine logs if it was greylisting.
