Mailman List:
I recently upgraded through rpm from 2.1.1 to 2.1.5. Just prior to upgrading one of my lists failed to deliver the messages to all members of a list. The mail server has a limit of 100 recipients per email. I configured mailman for a maximum recipents to 100. My list has 592 members.
Am I correct in my assumption that a message to this is broken out into 6 messages (5 with 100 recipients and 1 with 92)? The people who got the message have email addresses throughout the alphabet. Some of the addresses starting with w,f,k received it but then others like e,m, and some other w did not. How do I troubleshoot this and prevent it from happening again.
Several messages sent later in the day delivered fine without any problems.

It's going to depend a lot on your MTA and how it's configured, and whether or not you are making use of personalization features.

Even if you're not using personalization (so that Mailman creates the smallest number of messages possible and then hands those off to the MTA), the MTA may well deliver messages to the recipients in parallel. So, some users further down the list might receive the message before others higher, simply because of the difference in how fast/overloaded the recipient mail servers are, etc....

Without knowing extensive details of your configuration, it's going to be impossible to debug this process. Indeed, even on a mail server where I have full access to all available information, I can't always tell you what went wrong or what you should do to ensure that doesn't happen again.
And that's for customers who are paying me large sums of money for my consulting services.
