Information required on ERMS in CRM 5.0

Hi all,

I'm creating a demo on ERMS. I've done the configuration as said in How to Guide - ERMS system. Now I would like to know if we can trigger the ERMS1 workflow or test ERMS sending mail from one user to another in SAP system itself without any external mailing system.

Kindly let me know if this is possible and if yes let me know procedure for acheiving the same.

Cheers,

Prashanth
