Sorry for the slightly noob question here, but here goes.
Our company started really small, and as such, we had our mail hosted by
network solutions (yuck, I know). As we grew, I suggested and got approvak
to build us a mail server on BSD running Postfix. It works great, and I now
want to transition our mail system on to this server.
This is what I want to do:
For example, we have three email addresses:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
I want only bob to receive his mail on our new Postfix system, and bill and
Sheila to receive their mail on the old network solutions system. Is it
possible for postfix to basically go "okay, I don't know who
[EMAIL PROTECTED] is.I should forward this mail to the old network solutions
mail server!"
no, don't do this. instead do: "I know [EMAIL PROTECTED] should go to the
other server".
in this case, a simple transport entry suffices:
[EMAIL PROTECTED] relay:[other.server]
accepting addresses that would be rejected by the other server will
cause backscatter. so you need to know which address are valid.
In reality, it will be the other IT geeks and I receiving our mail on the
postfix server, while everyone else keeps using the Network Solutions one.
A gradual transition of a few users a day would be ideal (that way we can
catch any unforeseen bugs before it confuses the users).
