‡ Daily volume is the number of incoming SMTP connections.
† Windows 2003 server or better is always recommended for best performance.

Notes:
For volumes that regularly exceed 2,000,000 connections day, we recommend that 2 or more Alligate servers be installed in a clustered environment.

We always recommend that Alligate be installed on a dedicated computer. In most cases, it can be installed on your current mail server if desired. In these types of installations, we recommend that you
increase the system RAM to accommodate both Alligate as well as your mail server.

Alligate requires minimal disk space, however, as in all server applications, we recommend that you use a hard disk as fast as possible.
