And better alternatives exist - like qmail and djbdns. Is there any reason to run those pieces of shit besides legacy config files?

To quote the Makefile for /usr/ports/mail/qmail:

NO_PACKAGE= djb's packaging license does not allow non-standard qmail binary distributions

I would guess this is a big showstopper for using qmail in the FreeBSD basesystem. However, I think it was recently added some glue to sysinstall to let you choose MTA during install.

Perhaps, if it does exist, it is used for some authentication of sorts, when you initiate games online with it ?

I'm not sure how it works, I dont have one, but it seems to me connections through a medium, like some big gaming server, instead of direct connection between the two isps and hence the dreamcasts, would be a waste of bandwith.

The authentication could be to avoid country mixups, lets say it was Sonic adventure japanese and american ( heh if that game cannot use gaming online, forgive me on that, i dunno virtually anything about it )
Username: SonicAdventure
Password: here the japanese game connects to the american, hence tries a password like 'jappa'.
It cannot connect, the connection dies, and the game gives you an error. This could also work with version differences, if you can download some game-patches or similar that would change the two games.

that's about it
