[Mailman-Users] problems with the mail hostname

[Guillaume Rousse]

I'm having troubles with the name used by mailman for sending mails: it 
keeps using the real hostname, whereas it is configured for using an alias.

I have this setting in mm_cfg.py:
DEFAULT_EMAIL_HOST  = 'lists.zarb.org'
DEFAULT_URL_HOST    = 'lists.zarb.org'
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

All list configuration says also host_name is lists.zarb.org, all URLs 
are OK, but it keep sending mails as @katu3.zarb.org, instead of 
@lists.zarb.org. What is wrong there ?
