Default Postfix Email bounce - Connection error: 'Cannot resolve address.'

I have recently completed an install of the Community edition of Zarafa 6.20 on Ubuntu 8.04.

z-push works fine, so does SMTP inbound and WebAccess. But I am having an issue with outgoing mail -- i get a bounce message saying "Connection error: 'Cannot resolve address.'"

Here are the entries from spooler.log:
Fri Sep 26 10:53:30 2008: 0xb750cb90: Sending e-mail for user sam, subject: '<subject>', size: 8570
Fri Sep 26 10:53:30 2008: Connection error: 'Cannot resolve address.'.
Fri Sep 26 10:53:30 2008: 0xb750cb90: E-mail for user sam could not be sent, notifying user
Fri Sep 26 10:53:30 2008: 0xb750cb90: Removing failed message from queue

I used wireshark to sniff the traffic from the server -- it does not catch any attempt to connect out on port 25 but it does catch an attempt to resolve DNS for yes.samantix.com, a server I have never heard of or configured -- where is this server name coming from? I do not see it in any of the postfix or zarafa configuration files...
