[Mailman-Users] Email response very slow using Mailman and sendmail

[Patil, Manjiri S]

Hi Hank and mark , 

First of all thanks a lot for your detailed log explanation. I send new
message to this list today morning at 9:01AM and I received it arrived
at 10:02 AM. But some users havn't received it after 2hours. After
searching through logs I have come up with following. 

Also I see delay of 00:28:31 & 00:58:03 . I see that there is no
activity from 10:00:02 to 11:01:03. At 11:03 sendmail starts sending
message again to bunch of remaining people. I think delay happens when
there is stat=User unknown. I am going to unsubscribe those users. 


I do see that SENDAMAIL is trying to send messages only to bunch of
people which varies from 10 to 50 at time. Also how do I tune up
SENDMAIL with number of recipients to process at one time?
