Solution:

The following changes should be inserted into the file .muttrc in your home directory. This can be accomplished using your favorite text editor (pico, vi, emacs).

set spoolfile=imaps://imap.mail.gatech.edu/INBOX	# Define location of incoming messages
set folder=imaps://imap.mail.gatech.edu/INBOX		# Define directory where additional mailboxes are located
set imap_user=$USER				# Prevent mutt from prompting for username
set imap_force_ssl=yes				# Prompt for password just once per session

If the username on the machine where you will run mutt differs from your GT Account username, you will need to replace "$USER" with your GT Account username in the imap_user setting.
