"Old" messages are usually those which have the "O" flag set in the
"Status:" header. This status typically means that the message is
currently unread and was unread last time the mailbox was closed and
written. (Eg - exiting mutt w/unread messages will switch them from
showing as "N" to "O".)
See
http://www.expita.com/header1.html
about halfway down the page for the description of this header and a
list of possible values. It's RFC2822 _compliant_, but not standard.
If you didn't see this before switching ISPs, are you (or they) by
chance doing any processing of the incoming messages on the new ISP's
server? I'm just wondering if the mail is passing through anything
that might set the flag on its way to final delivery.
