Coldfusion On Suse Enterprise Server 10

Coldfusion is not sending emails and is showing a java error in the coldfusion administrator if the "verify mail server" box is checked when submitting the mail settings.

The mail settings are right (they work on our production server), and I can send mail from the command line on the machine so there are no problems with the MTA or with a firewall.

I am running coldfusion 8 on SuSE 10 enterprise server. Has anyone else had this problem with coldfusion 8 and SuSE 10?

Any suggestions would be greatly appreciated.

Thanks
