Perhaps they simply didn't all go through the same server. Look at
your received mail headers to see which RH mail server(s) is/are
involved in your question.
I'm not with RedHat in any way, but:
It seems more likely to me that the cause of the inconsistency is due to
the ip address of sender's email server is changing. I can't imagine an
organization like RH implementing greylisting in such a spotty fashion.
The three things that most greylist software looks for are:
1) ip address of the sender's mail relay
2) "To:" address
3) "From:" address
So if any of these are different, your message will get greylisted.
