Exchange 2003 TLS emails stuck in queue and not delivering from outside

I have a Exchange 2003 environment with one FE and two BE servers.  We have one vendor who has to send everything encrypted so we set up a TLS enabled SMTP on the FE server which is receiving emails correctly.  Those emails are stuck in the FE server queue and not getting sent to either of the BE servers.  Any ideas?

Thanks,
Bg

Got it figured out.  Had to disable TLS on the Secure SMTP server in the Delivery tab - Outbound Security section.  That apparently doesn't effect emails going between TLS enabled organizations as several test emails have gone successfully through as expected.

I also moved my mailbox to another BE server to isolate if both BE servers would have the same problem.  Should have the results soon.
