MTA show POA as closed - no path configured

I migrated from Netware 6.5 to SLES 10.1
Gwise 7.1

After migration and install of Gwise agents on SLES the MTA gui shows the
Post Office as closed.
Below is an extract from the log file.

13:06:02 488 PARL_DOM: Begin opening domain
13:06:02 488 PARL_DOM: Domain now open
13:06:02 952 PARL_POST: Begin opening post office
13:06:02 952 PARL_POST: Closure reason: No path configured

I checked the path for both agents in C1 and they are correct. So what
could be the problem?
