Something is clearly going wrong. Try 'strace -p 14058' (the process currently listening) in one window while you telnet in another.
Nothing prints.
Before tracing anything (processes or network traffic) the OP should check the maillog. It for sure will the the truth about what is going on.
Here's some of the printout from that log:
