Jonathan, You are once again correct. POP3 is really an older protocol which allows for batch downloading of emails. A POP3 server needs to be queried by each client every time an update is desired. IMAP is newer and appears to "push" emails to each client immediately upon receipt. The actions on each client are also relayed back to the server so that read, delete, re-label, move to folder, and respond actions are reflected at the server and ALL of the other clients.
POP3 was/is great for low bandwidth applications where you may need to minimize connection time and data usage. Old ISP's with limited data or minutes and sailmail come to mind. connect - download - disconnect - read - compose - connect - upload - disconnect. IMAP works great for always on highspeed connections that can support the constant back and forth syncing of emails. Most people, with modern internet connections can, and probably should, use IMAP service. Even if you don't have or don't want constant syncing most people will control this simply by turning on/off the internet connection. IMAP figures it out automatically. http://www.upperhost.com/pop3imap.htm Josh Muckley S/V Sea Hawk Marek Are you sure about this? I have no problem reading emails when my phone is in airline mode. Of course it is not getting new emails but that is the same with Pop3 -- Jonathan Indigo C&C 35III SOUTHPORT CT On Mar 15, 2015, at 22:28, Marek Dziedzic via CnC-List < cnc-list@cnc-list.com> wrote: If you switch to IMAP (from POP3) you lose the ability to read off-line - for some this might be useful. _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
