Correct me if I'm wrong, but my personal opinion is that this reason is 
nonsense. (Okay, I guess that could be phrased more diplomatically, but hear 
me out).

Although email quite often is comparable to instant messaging, email was not 
designed to be instant. Hence delays can and will happen.

So if email is really that critical that it is not permissable to delay it 
with greylisting, well, then that information should not have been sent by 
email in the first place.

As a sidenote, I'm using several antispam techniques with mimedefang, among 
them I'm doing greylisting based on spamassassin hits so only possible and 
definite spam mails will be greylisted. This way most regular mails will be 
received directly while the spammy ones will be greylisted. Admitted, it 
wouldn't help you very much since it still means that occasionally a regular 
mail will get greylisted.

Just my two cents. :)

Guido
