Okay, so look for more lines like this in your postfix log, specifically 
you're looking for lines with a high value in the "delay=" field.

That just tells you how long it took for Mailman to hand off the message to 
postfix.  If there was a significant delay internal to Mailman, it would 
show up here.  But everything you've said so far indicates that the delays 
you're seeing may not be internal to Mailman.  So, you need to look in the 
MTA logs, too.

Maybe you are rate-limited by your ISP?  They only allow you to send so many 
messages per hour, and with your mailing lists you easily exceed those 
limits at lunchtime?

That's a question you'll need to take to your ISP and have them answer for you.
