I've terminated to configure my server but when I create a list, the welcome message stops on queue. Analysing /var/log/mailman/smtp-failure I get:
Oct 29 09:04:29 2009 (18551) delivery to email@example.com failed with code -1: (101, 'Network is unreachable')
Could anyone help?
This is more a question for firstname.lastname@example.org, but ...
Mailman is unable to connect the the SMTP server defined as SMTPHOST in Defaults.py/mm_cfg.py. This is normally 'localhost'.
