Mac Equivalent to Exchange Server

[madman045]

Can anyone tell me what the equivalent of exchange server is for Mac?

Or am I going to be putting quickmail server back onto a new Mac Server?

Thanks

you mean a full-on groupware server, or just a subset (e.g. mail)?

Well at the moment they have a G4 Mac Server with Quickmail Pro Server installed collecting from a pop box and distributing to users.

However they need a server where by they can save their files and have it backed up, but move to Entourage for email.

The other thing is that they are going to be opening a second site in the next few months and that will require email aswell.

The idea was to have exchange type server in one site collecting all email and another server in the second site linked to the first, syncronising via a perminent VPN tunnel...
