We have a BM 3.8 SP5 server that is doing mail proxy for a GroupWise 7 SP3 server. Yesterday, after a BM server reboot, we can only send to a limited number of domains. Most mail sent out comes back as
Undelivered mail : Unknown user: ..............
I tried a different DNS server address on the BM server, but that didn't seem to make any difference.
Also, I should mention that the BM server seems to hang for several minutes when trying to load brdsrv.nlm on restarts.
I am not the one that originally set this up and I am not sure why we are using mail proxy as we have several free public IPs.
