I have the problem that the incoming mail is not deliverd to the GroupWise
GWIA.The received mail is deleted from the spool/incoming directory en
never reaches the GWIA

- Mailproxy in BM is enabled towards the gwia
- Telnet to mailproxy works well from external
- Telnet to GWIA worsk well
- Mail is deleted from incoming spooldirectory
- Mail Proxy Statistics in Application proxy displays a number of
received/stored messages and a number of Intended recipients

This append at once a few days ago.
Does anyone have a suggestion?
