Subject: [Leica] Re: Slow delivery of LUG digest

It is good to get the LUG digest as fast as possible.
However, if you are seeing delays in the delivery of your LUG digests I
assure you that it has nothing to do with the "Priority:" field. 

Mail delivery is handled by the software on my computer. I am using a
program called "sendmail 8.9.1" to do the mail delivery. The message is
put into a delivery queue here, and the sendmail program delivers it by
opening a network connection to each recipient, sending the mail over
that connection, and then closing the connection.

"Priority" declarations in email are largely ignored, but when they are
obeyed, they are used by the sending program to help it choose which
queued-up message to send first. If there are 10 outbound messages
scheduled for delivery from the same computer, and one of them has a
higher priority than the others, and if the sending mail program obeys
priorities, then it will send that one first.

If you are seeing a delay in mail delivery, it is because the people in
front of you in line are taking longer to accept delivery of their mail.

You (Pieter) are the 291st person on the leica-users-digest list. This
means that delivery will be attempted on your mail after it has been
attempt4ed on the 290 people in front of you. 

I pay a certain amount of attention to delivery times, and when I see
that someone's computer is always slow, I move them to the end of the
list. In extreme cases, I move them to a separate list, leica3, whose
only purpose is preventing very-very-slow deliveries from getting in
front of other people in line.
