I'm in page 5 at the end of Step 11. I'm telnetting in locally and after connecting, the session becomes unresponsive. I've restarted Postfix and it starts fine but restarting the SASL Daemon fails. I'd like to continue from here if possible. If not, do I need to remove the packages I installed at the beginning of Step 11 or can I simply redo those steps? Shoot. Will that even fix the issue?
