All this was in ruserpass.c...

ruserpass(host,&user,&pass); is found in msgchk.c, in checkremote() or
something like that... meaning that the host aren't vulnerable if not
configured.. this is from a system where mh was installed w/o being
configured (default)

[nolander () sangis nolander]$ /usr/bin/mh/msgchk -host muroff
msgchk: no servers available

check mana mh-tailor for more info about this server stuff :)
