[ale] Sendmail and MTA

[jtholmes]

I want to make this short.
If not enough details then I can provide more.
Sendmail usually Xfers to  a Mail Transfer Agent (Usually another
instance of Sendmail)

Situation.
Several Linux boxes in a MS Windows env, on Bell South DSL.
Bell South DSL connection currently acts as MTA

Needed
Ability for all on the Local lan both Linux and Windozs to
be able to email locally and to the Internet.
Dont want to use MS Exchange
Is Outlook capable of talking to an MTA

Is this a viable solution

One Linux box acting as Local MTA
Local MTA Linux forwards Outbound (not for local lan) to Bell South MTA
All other Linux boxes forwarding to local MTA
All Windows  boxes do What?  Evolution? Would like to use some MS product
  to keep things simple for those poor Windows users.

Thanks
