The server is just an SMTP inbound/outbound server but "DNS Blacklist Filters" is enabled in the Config doc. We do get an awful lot of spam from a server in Brazil, hence the enablement. Again, the server is gets considerable SMTP connections.
The Domino server version is 6.5.1
The CPU is a PII 450 and 512MB
The notes.ini is just a standard one with the mailScan stuff added
Scanner is f-prot for windows (latest defs, patches, etc)
The only thing I can see that maybe screwing it up, is that SAV For Domino "used" to be installed. I'm in the process if moving the SMTP to a w2k server box on 6.5.1. with a virgin install of w2k. I have a feeling this will clear up my issues.
One other thing I did notice was that the server only appears to crash when it detects a virus. It would then NSD, restart the Domino service and recan the email correctly and remove the virus. Then next detected virus would repeat the process just described.
I'm not able to access the box today, but if any of the info is incorrect I'll update you tomorrow and post the notes.ini
