[Mailman-Users] Mailman receives posts but no sent them

[NetBiker]

Hello,

I've enabled mailing lists with Mailman 2.1.2 and Postfix in a Mac OS
X Server 10.3.9

I've the following errors when a subscribed user sent a post to the list:

logs/smtp
Oct 30 16:52:39 2008 (378) All recipients refused: (7, 'No address
associated with nodename')
Oct 30 16:52:39 2008 (378) All recipients refused: (7, 'No address

<Pine.LNX.4.64.0810301651440.26490 at server.dom.ain.one> smtp for 3
recips, completed in 0.059 seconds

3 failures

the list prueba has three subscribers

the same problem occurs with other messages in the list

mailman-bounces at dom.ain, size=605,
message-id=<mailman.5.1225229913.12728.prueba at dom.ain>, 1 failures

No messages or posts were sent since the list was created but in the
list archives we can see all the posts

Postfix is working fine with messages for the dom.ain domain in the
same Mac OS X server

we only added in the mm_cfg.py file:

DEFAULT_EMAIL_HOST = 'dom.ain'
DEFAULT_URL_HOST = 'lists.dom.ain'

add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)


thank you very much
