[Mailman-Users] mailman not delivering mail

[Eric Beda]

Mailman doesn't send email, i get this in my maillog

to=<dmis-staff at pmoralg.go.tz>, relay=local, delay=60,
delays=60/0.01/0/0.18, dsn=2.0.0, status=sent (delivered to command:
/usr/lib/mailman/mail/mailman post dmis-staff)

but the mails are never delivered to the users mailboxes, and are not even
archived ( i set it to archive daily)

i've checked that mailman is running

./mailmanctl  status
mailman (pid 6729) is running...

don't know what else could be the problem,,

please shed some light
