[Mailman-Users] slow delivery times

[Paul Key]

Using Mailman version: 2.1.3
Solaris 9

Hi

I am having a problem of delayed or slow delivery of emails of a list 
with around 1600 subscribers.  Below is an Exim log for a small 
testlist.  Where does the <= testlist-bounces at mailman.sghms.ac.uk come 
from? I assume mailman sends this - what is it for?  can it be turned 
off?  could it slow the list processing down and so the delivery of emails?

Any other ideas as to why the mailman is sending out emails slowly over 
a long period of time and how delivery can be speeded up?

Thanks

Paul
