Resolution
- 
Launch ConsoleOne

From the dropdown, select Gateways then select the GWIA
 - 
Under the SMTP/MIME Tab select Address Handling
 - 
Uncheck the box'Do not replace underscores with spaces'
 - 
Also verify this setting is not being set manually in the gwia.cfg (which will take priority over settings set via ConsoleOne)

Go to /opt/novell/groupwise/agents/share and modify the gwia.cfg
 - 
Search for the switch --dontreplaceunderscore and verify it's commented out with a ;
Example: ;--dontreplaceunderscore
