Hi guys,

I've run into an interesting little dilemma. I noticed the problem
with an alias for an account that listed itself and another local
address for delivery. The account itself only gets one copy but the
other local address gets two copies. I even tried adding a third non
local account to the alias and that also only got one copy. I then
tried having the alias only delivery to the alternate local address
and it still went through twice.

For various reasons our old mail server is still MX for all of our
mail and it's then relaying mail to the new server for those
domains/users that have been migrated. Delivery direct to the new mail
server doesn't result in this problem. I'm not sure where to start
looking at the cause of this. Can anyone tell me what I'm doing wrong
or point me at the documentation that would explain what's going on
here.

Thanks for any help.
Guy
