[Mailman-Users] Slows down takes days to send the mail.

[SpookyPlaces]

Does anyone have any ideas why all of my mailman mailing lists have slowed 
down and takes days for them to send the mail out ?

I have several on two different domains and they have all slowed down.  At 
last check it was taking 3 to 4 days for them to send the mail.  I have a 
feeling it may be taking longer now.
