to avoid incurring any encryption/decryption overhead, if you are in a trusted 
network and if both machines have netcat (you probably can get netcat for 
windows by installing cygwin) you can try the following:

on the workstation do:

nc -l -p 6000 > my12gigFile

and on the mailserver do:

nc -q myWorkstationIP 6000 < my12gigFile

that is the quickest way to get the file across as far as i know. however, in 
my experience, the best way to move really large files across is to place the 
file under a webserver and then use wget with the -c option; since, it seems, 
that you inevitably run into problems midway thru the long transfer and 
having the ability to continue where you left off is worth the overhead of 
http. if you do end up using ftp, look into tftp.

hope it helps.
