Duplicate mail

["Mark" <marq@xxxxxxxxxxxx>]

I have been on the metastock list for at several weeks now.  Everything was
working fine, then one day last week all messages from the list server
started to come duplicated i.e. two identical messages from each contributor
and this has continued to this day.  This is annoying because I have to
delete every second message manually since I save and archive my email and I
don't want to take up any more space than necessary.  Is this happening to
anyone else?

Thanks,

Mark.
