[Cialug] Postini and Graylisting - Solved

[Claus]

Todd,

My picture is as follows:
   Postini > Internet > greylist-box > client Inbox

So I'm already happily running postfix with postgray for many years.  It 
does a great job in avoiding spam and I haven't missed many mails.

The issue I have is that someone I now need to communicate with uses 
Postini for their outbound emails.  Postini strangely tried to deliver 
the email exactly once. It didn't even try sending the message from a 
different IP.

The true problem I guess is that I forgot about the whitelist of 
postgrey.  Things were just running to great for too long. LOL! Looking 
at the latest release of postgrey I see an entry for postini.com.  I 
updated the white list and I should be fine for the next few years until 
I will have forgotten all this again.
