Here is additional verification that IMAP and all ports are working on my server:

Hi,

I've checked to see that port 110, 143, and 25 are all open and listening.

-bash-2.05b# hostname
vps.youngcomposers.com

-bash-2.05b# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK Hello there.

-bash-2.05b# telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Apparently the error is not on my end, and a potential bug in the software installation process.
