After purchasing the pro version and begin using the graphical console, we detect that modifying the configurations of mailing lists, these do not display correctly paragraph "Mail Deliver Restriction" and some of them were corrupted to modify them. By the time we continue using "command line tool".
The error obtained with the command "python maillist_admin.py info example@exmaple.net" is the following:
Traceback (most recent call last):
  File "maillist_admin.py", line 122, in <module>
    print '{0}={1}'.format(k, v)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf3' in position 26: ordinal not in range(128)

Thank you and a greeting,
