[Mailman-Users] Log entries refer to which list?

[Allan Trick]

I was trying to determine if a message was sent to the lists it 
should have been sent to, and see two different types of entries in 
my SMTP log:

>Aug 24 16:23:57 2006 (18946) 
><6.2.3.4.2.20060824161925.02ded760 at mail.prin.edu> smtp for 41 
>recips, completed in 8.864 seconds
>
>Aug 24 16:23:58 2006 (18946) 
><mailman.0.1156454519.18944.2012 at mail.prin.edu> smtp for 1 recips, 
>completed in 0.296 seconds

Does the first line indicate the sending of a message to one list, 
which has 41 members?  Is there one line like this per list that 
receives a message?  If so, how does one determine which list that is?

And what would the difference be in the second example?  I'm guessing 
that is referring to maybe an umbrella list that was sent to.

Thanks!
