[Mailman-Users] Email delays using Mailman and sendmail

[Patil, Manjiri S]

Hi, 

We have internal Mailing List server running Mailman 2.1.9 and SENDMAIL
8.13.8. Whenever someone sent email to particular mailing list
(everyone at managemant.bu.edu)consisting app 300 users recipients receive
it after several hours. E.g see the following Email I sent yesterday at
3:19PM that came in at 6:09 PM and some received at 7:09 PM. I don't
understand why there is so much delay when sending mail to 300 users
mailing list as oppose to Sending mail to 140 users list. 

Following is the part of SENDMAIL log when I sent message yesterday at
3:19PM

How do I debug the problem ? Pls help .
