Some further details:

Alpine never loads what it does not need.  If the user has 10,000 messages 
in his mailbox, butis focused on the last 20, then Alpine never accesses 
any data on the first 9980 message.

Alpine does partial fetching.  It has the IMAP server parse the message, 
both for headers (RFC 2822 parsing) and body (MIME parsing).  It generally 
does NOT fetch MIME attachments unless the user specifically asks for it.

Thus, I can read a message with an attached 60MB video clip over slow 
wireless (e.g., EDGE), as Alpine will only fetch the text parts of the 
message and not fetch the video clip unless I ask for it.
