Secondly, after installing the toaster do I need to setup logrotate to rotate any files for qmail, vpopmail, etc...? My main concern is qmail.
Nope. This toaster install uses multilog, which rotates logs for you.
One of the things I love about this is the smallness of the default logs, 10x100k ... on a busy system your logs span the last hour or two at most :)
Then again it can make troubleshooting a challenge as well, luckily it rarely breaks, using qmailmrtg helps so you will know when something strange is happening.
