i have sbs 2003 with all the lastest updates installed, but users get duplicate e-mails when the sender uses multiple reciepents. e.g. if some1 sends a mail to "user@foo.com; user1@foo.com" both user and user1 will get 2 mails. any ideas??
thanks

It seems to be a problem with the mail provider. You need to check with your provider and see if they are able to change the way they handle your pop email.

hi,
Disable any archival features on the server.
Disable antivirus scanning both on the server and on the workstation. (This step should only be temporary as a test. Do not disable it permanently.)

Does this happen only for external addresses, or does it also happen for internal (within same SMTP domain) addresses? Does it happen all the time, or intermittently? If you were to include me on such a message (uemurad@yahoo.com), would you expect the same thing to happen? If the message is addressed to three people, do three messages appear?

When you look at Message Tracking, does it show multiple deliveries? Are the timestamps the same, or is there a time gap between the first and second messages?

thanks

User, just a silly question - is the outlook client also configured to bring down pop3 mail as well as connect to the Exchange server (e.g. is there a pop3 setting in the MAPI profile?)

Cheers
