[Greylist-users] Important emails are delayed by up to four hours - if we implement postgrey (greylisting).

[Chuck Amadi]

Hi List

I posted a email regarding if

Hi List

A colleague has some reservations about greylisting in general because 
of the inherent delays that would be introduced.

My Colleague views below:

I am concerned that the top management will not be impressed when 
important emails are delayed by up to four hours, especially since that 
delay is dependent entirely on the third party's mail server retry 
schedule, and thus beyond our control to configure.

I have installed postfix and postgrey at my last employer and I didn't 
see any issues but are the above reservations warranted As I thought the 
longest possible delay
in 5 mins using the default settings and once whitelisted will never 
have to go through the grey listing process again plus the the fact I 
could also pre add any important email
address or domains to whitelist_clients list which again avoid going 
through grey listing process.

Please advise and if possible any good links So I can read and digest as 
I personally I would like to implement grey listing as part of our 
strategy to
reduce UCE.

Cheers
