I do not believe that there is any facility in the POP protocol to "re-sync back to the POP server". It's a "store and retrieve [and delete]" (initially "retrieve only once") protocol.
Once a mail client tries to include "special capabilities" that aren't standards-compliant things can easily go off the rails. Something that may work with one server configuration may not work with the next, etc. Not a direction one needing to support the software ever wants to go in. A good (standards-compliant) IMAP client is very flexible and will let you manage your mail most any way you want. The ability to move messages between (server-side) folders from a client makes it so that you can have things show up where you want them *in any client/in your mail-viewing environment of the moment*. I.e., your mail view is consistent regardless of what you are using. Not something you can do in POP. I have never found the mail client-centric approach to mail that is POP very useful in a multi-environment world. POP may work well for you, but it's not a very robust protocol and the specification isn't likely to advance very fast. > Date: Saturday, January 23, 2016 13:46:17 +0000 > From: Paul Hudson <paul.g.hud...@gmail.com> > > Hi Richard, > > Yes, it's in regard to a POP account.
