<div>The company I work with has looked into purchasing an IronPort, Symantec 8160, or possibly a CipherTrust solution (6.0 will have 'greylisting'). They all seem to do a 'custom' form of greylisting, but each box has minimal functionality. It seems like an enterprise solution should be robust and have all the capabilities that the boxes are built with. For example, the CipherTrust solution is actually a FreeBSD box, but the shell only has a hand full of commands. You don't even get access to chron to set up automated backups. I understand that giving extended shell access would probably cause a significant increase in helpdesk calls, but is seems that an enterprise solution would required this kind of configuration.
