I would argue the opposite.  POP3 creates more load, especially on the  
network side of things, since it requires the client to download the  
full headers vs. individual fields.

And viewing messages is a much greater load on POP3, especially when  
viewing MIME messages with attachments since you necessarily need to  
download the entire message to view vs. downloading only the structure  
(and generally small text parts) when using IMAP.
