You can either
* try to patch SQLgrey to accept connections on an UDP port instead of 
the default TCP :
- search for "my $server = bless {"
- 3 lines below, hardcode your desired UDP port like this :
- port = <yourport>,
  proto = 'udp',
if it works, you'll have to maintain your own SQLgrey branch.
* or write a wrapper that will speak with your server with a protocol it 
can understand and with the Postfix protocol with SQLgrey (more complex 
but better as it means you can switch to whatever policy daemon you want 
and won't have to maintain your own version of SQLgrey). For a simple 
protocol description have a look at 
http://www.postfix.org/SMTPD_POLICY_README.html.

You'll be on your own for this though, I can't test this as I don't have 
access to your mail-server and am not inclined to spend time on 
integration with other SMTP servers anyway.
