[Az-Geocaching] Duplicate Downloads?

I download my email into Outlook. From time to time when I post to the
listserv, my message will show up in my inbox twice. But I've never seen it
duplicated in the mailing list archives, so I never worried about it. Today
I got dupes of everyone's messages, but again I don't see any duplication in
the archives. So I assume it's something in my configuration that's hosed.
Anyone have any ideas? It's just a minor annoyance.
