Does anyone else consistently receive ruby-talk messages out of order?
I will often receive two or three replies to an original post before
the original post arrives.

I looked at the Received: headers in a few cases and see that the mail
is arriving out of order to the mac.com mail servers.  The next
upstream server is beryllium.ruby-lang.org and the Recieved: headers
for that host show the messages in order.  So for some reason the
messages are getting reordered in the queue between beryllium
and mac.com.
