You might want to update that cf file. But that shouldn't have
any bearing on your question.
I was just thinking about this the other day. I'd been having
problems with all my mail because of an IP change and wanted to do
some analysis. Your mail gives me an opportunity to explore this
further. I'm going to calculate a "delay" by subtracting the Date
field from the Delivery-Date field and see what that shows me.
The first thing that I found is that lots of people don't seem to
care what time it is. At least one messages had Date: that was as
much as 22 years in the future. Several were from one or two years
out there. All though no messages had dates before 2000
There are 2011 messages from 'questions', 'stable' and 'small'
sitting in my freebsd MH folder. I found that 1745 had "delays"
that were between 0 and 6 days. Of these I saw two major delay
and flood events that correspond to local network problems.
Outside of those flooding events I did not see anything that
indicated other than normal human cercarian behavior. Of course
my sample was pretty small.
