I am trying to set up BM3.8 in my LAN for the first time.
Local mail server running in LAN (NIMS3.0).
When BM is up (no matter if mail proxy service is on or off) NIMS will not
comunicate with external mail server or internet at all. Same with clients
which use aditional accounts (other then local mail server). Sending or
receiving mail from/to outside mail servers don't work.
When BM down mail comunication is ok.

Where is the catch?
