Diff between Supervise & Tcpserver?

[Brett Randall]

Hi guys. This is probly a simple question but I can't find an obvious answer anywhere.As far as I can tell, there are three ways to run Qmail: Inetd (yuck), tcpserver (regular), and supervisor (??). I have set up a new master qmail server up with supervisor (just for testing sake) and it runs fine, but all my other qmail servers run tcpserver with no probs as well. Can anyone tell me what the difference is between simply running a qmail smtp daemon through tcpserver, and setting up all the weird supervisor stuff is? I have to document it in layman's terms for a client, and don't really know advantages/disadvantages of either.   Thanks,   BR
