GWIA does not accept messages from Barracuda

Hi all,

--------------------
NetWare 6.5 SP7
GroupWise 6.5.6
--------------------

GWIA sends out to the Internet without problems

GWIA does not accept emails from the Barracuda anti-spam unit.
Putting logging into Diagnose mode I can see GWIA accepting a
connection from the Barracuda, it increases the message number but
does not pick up anything, not even to the point of queuing to the
MTA. The Barracuda is on the internal network, so on the same network
as the GWIA.

It gets stranger. The photocopiers can successfully send scans to the
GWIA and I am starting to suspect that this is because the email
addresses of the photocopiers have the same domain name (ie. they are
not the sort of external addresses that would come through the
Barracuda).

There is nothing wrong with the Barracuda as we can get it to deliver
to another SMTP program which we can then interface with the old
GroupWise API gateway (GWAPI) as a temporary workaround.

Any ideas ?
