sudo netstat -l -n -t -p

no 8001. -p means list the names of the processes listining. The output
will be a list of all the processes listening on TCP ports. Look for
port 8001 in that list. If it's not there, nothing is listening on 8001.
If it is, the name of the process will be listed.

Here's a sample output:

This is mailman listening on port 8001

So  maybe nothing is listening on 8001.

The conflict would be if some other process was listening on 8001,
Mailman wouldn't be able to.

Have you started mailman (mailman start)?
