I can telnet in port 143 from inside and outside the server. I just cannot

perfectly. Here is my dovecot config:

Which dovecot version?
There are packages of dovecot-2.0.11 for CentOS/QMT in the QTP repo. You
can install it with yum. If you didn't install dovecot with rpm, you
should "make uninstall" it first.
That being said, I'm guessing that your client doesn't have TLS or
secure logins enabled with port 143. Since you have
"disable_plaintext_auth = yes", dovecot will not allow logins with
passwords that are sent in the clear (which is a good thing). To use
port 143, clients need either secure logins (cram-md5) or TLS enabled.
TLS is preferred, as it will encrypt the entire connection. Note, that
TLS on port 143 is also preferred over IMAP/SSL on port 993.
