Bizarre mail forwarding issue

Hi Guys,

I have a clean (or I assume it was clean but I didnt do it but it was brand new Xserve G5 from the NZ Apple distributor who did do the setup) install of Panther Server 10.3.6. Everything works fine except for one persons mail. There are only 20 users, all of which have two email alias. joe@example.com, and j.bloggs@example.com. Of course joe@example.com is the first entry in WGM as it doesnt allow periods. For one user, and one user only, the first entry works (ie they can receive mail on joe@example.com) but when you try and send mail to j.bloggs@example.com you get a bounce saying the Mailbox "Kathelene" doesnt exist. The server logs indicate that the address j.bloggs@example.com is being forwarded to kathlene@example.com. The problem I have here is kathlene of course doesnt exist and never has.

WGM doesnt indicate that this redirection exits (as can be seen by the fact joe@example.com works). Where can I look in the actual config files to find this supposed redirection and remove it.

Thanks
