[Serusers] Problem with SIMPLE2Jabber gateway

Hi, I trying to doing a proof of concept using Windows Messenger and SER (SIMPLE2Jabber Gateway). I have SER (0.8.11-0) installed and running on Redhat-9 (Linux 2.4.20-8). I'm using Windows Messenger (Version 4.7) as my client. It seems like the Windows Messenger clients are able to register with the SER. But when I try to send an IM between the clients nothing happens and I see the following error in the log file: Dec 8 16:45:42 yosh-cm1 ser: 0(2234) XJA:xj_address_translation:2249: - wrong Jabber destination yoshioka(a)yosh-cm1.cisco.com!!! Dec 8 16:45:42 yosh-cm1 ser: 0(2234) XJAB:xj_worker:2249: ERROR SENDING as Jabber message ... Any help would be appreciated. Thanks, Alana
