Comments on: Understanding POP3 mail client duplicates http://www.everything-mdaemon.com/mdaemon/understanding-pop3-mail-client-duplicates Everything you've ever wanted to know about MDaemon Thu, 04 Mar 2010 18:29:07 -0800 http://wordpress.org/?v=2.9.2 hourly 1 By: Dave Warren http://www.everything-mdaemon.com/mdaemon/understanding-pop3-mail-client-duplicates/comment-page-1#comment-422 Dave Warren Sun, 15 Nov 2009 05:34:22 +0000 http://www.everything-mdaemon.com/?p=13#comment-422 Randolf, You're half right -- LAST is a POP3 command, it tracks the last message retrieved using RETR. The neat part about it is that it works across sessions, so it works as a poor man's "find new messages", but you have to understand how it interacts with multiple clients accessing one account. HEAD doesn't exist, I was actually thinking of NNTP (where you can retrieve headers, the body, or the entire article) However, you can emulate "HEAD" by using "TOP" and requesting 0 lines. I've updated the article appropriately, thanks for the feedback! Randolf,

For HEAD, you're probably thinking of HTTP. In POP3 the HEAD and LAST commands don’t exist. For HEAD, you’re probably thinking of HTTP.
