Help - I receive triplicates of all emails

[Amy]

The deal:
On earthlink webmail, I only receive one of each email.
When I "Send/Receive" from Outlook 2000, the Send/Receive
window tells me I'm receiving 10 emails, but 30 appear in
my inbox. Everything arrives in triplicate or duplicate.
Extended headers appear to be the same in all three
identical emails.

Things I've tried and know:
Deleted and then reconfigured my earthlink account many
times. There is only one earthlink account.
"Leave a copy of messages on server" is unchecked.
Turned Earhlink Spamblocker On then Off then On then
Off... no change.
Sent test messages from other accounts to earthlink - on
webmail there's only ever one message, in outlook there
are triplicates or duplicates.
Ran MS Office 200 Repair Tool.

Anyone have any ideas about what's going on? What else
can I try? Thanks in advance for your advice.

Amy

Do you perhaps have a rule set up that might be creating copies of the
messages?
