I send 1, they get 20

[damn]

Hello,

A little while back one of my users showed me an example of how an email she was sent turned up as around 20 exact copies in her inbox. I brushed it off as the senders problem.

The other day, I sent an email from an external account, to a user who is on my FreeBSD 5.2.1 / DA box. I sent 1 copy, he got around 20.

Checking the exim mainlog, it shows that the email was only received once:



2005-02-25 17:45:41 1D4ZEK-0001sP-VJ <= admin@external.com.au H=mail.external.net [xxx.xxx.xxx.xxx] P=smtp S=17494 T="RE: Radiology" from <admin@external.com.au> for ian.d@client.org.au
2005-02-25 17:45:41 1D4ZEK-0001sP-VJ => ian.d <ian.d@client.org.au> F=<admin@external.com.au> R=virtual_user T=virtual_localdelivery S=17651
2005-02-25 17:45:41 1D4ZEK-0001sP-VJ Completed


Anybody else seen / heard of this? Given the logs only show one instance of it, I don't know where to start.

First place to start would be to check the Message-ID of each message. Are they the same?

With that information, I'd find a good support channel for the POP daemon.

I started by setting the PC in question to leave mail in the mailbox.

This way I could look at the account via webmail & see that there was only 1 copy on the server.

My notebook can download the mail correctly, receiving only 1 copy of each message.

I checked the message ID, they are all the same.

Its happened to a few machines in this one office, so I'm now going down the virus / spyware / adware route.
