It looks like you aslo removed the daemontools as well, so you'll want to remove the line
Code:
SV:123456:respawn:/command/svscanboot
from your /etc/inittab and then 'killall -HUP init' to re-read the inittab and stop the attempts to spawn svscan.
After you get that, make sure you have no leftover processes running such as qmail, tcpserver.
Too bad you had to delete qmail as it's my all-time fave MTA.
