The email address of the sender of the post doesn't pass the test in
mailman/email/validate.py. This means it contains a space or begins with
a '-' or contains or a non-printable ascii character or an ascii
printable character in the set


It also must be a fully qualified address with at least one '.' in the

log.debug() will write a 'debug' level log message to the log file which
is defined in the 'log' instance.

For example, just to pick one, the module mailman/mta/connection.py contains

to the 'smtp' log with level = debug

We are trying to get there. We will have a mailman3-users at mailman3.org
list running under Mailman 3, but we're not quite there yet. In the mean
time mailman-developers at python.org is the best place for Mailman 3 issues.
