[Mailman-Users] Message queued

[Xavier NOEL-LARDIN]

hello,

I have just install a server, redHat 7.2 with the sendmail in default and 
mailman 2.0.5. I am installing this server for tests in the society.
I have a redhat server 7.1 with the same distribution of mailman and this 
work fine.(and people are happy)

On the new server when i send a mail to the list, the message is queued. 
When i go to the maillog i see : stat=queued

What can i do to resolve this poblem ?

thanks in advance.

regards
