Lotus Domino

For our domino services we primarily use IBM Lotus Domino on an enterprise-class sparc64 machine running Sun Solaris. Needless to say, these services are running in their own, seperate VLAN, firewalled from the outside and all other internal networks. And of course we monitor it 24/7/365. Mail is relayed through our high performance mail platform, the domino smtp task is not directly reachable.
