[Mailman-Users] list not accepts mails

[deconya]

Hi

Im using mailman and Im having a problem only with one list. When I
send a mail only appears logs in two files, smtp and vette. The list
has the moderation bit activated, but never arrives to the queue.

first appears:

Nov 07 17:11:48 2011 (5454)
<mailman.0.1320682307.18316.alum at lists.esci.es> smtp to alum for 1
recips, completed in 0.024 seconds
Nov 07 17:11:48 2011 (5454)
<mailman.1.1320682307.18316.alum at lists.esci.es> smtp to alum for 4
recips, completed in 0.064 seconds

and finally in vette log:
Nov 07 17:12:42 2011 (5452) Message discarded, msgid:
<1320682361.4077.1.camel at infolinux>

I can't localize any error but it's a big list (1300 users) and the
log is so strange no?

Any idea?

Thanks
