Dave,
You need to use an imap server, I do not know if gmail has this or
not, as pop (IIRC) does not allow you to grab headers and download /
leave on the server.
If I am wrong please do not shoot me, as I am not 100% sure, but
have always set users up with imap when they have asked for this
feature.
Eudora can do it, somewhat skankily :)
My usual solution is to designate one machine as the 'canonical'
machine tha I want the full archive of my mail to turn up on
eventually. This machine is set to download immediately.
The other machine I set to leave mail on server. I quit each mail
client when I'm finished using it at that location.
Works for me, but that's with Eudora, don't know how well it'd work
with Mail.app
Have fun,
Shay
