Maybe a bit offtopic, Sieve beaviour

[Sean Kamath]

I recommend reading the RFC: 2.10.2 <https://www.rfc-editor.org/rfc/rfc5228#section-2.10.2> is where the Implicit Keep is described.

Basically, if you don’t take action on a message, there is an “implicit keep” that will save the mail in the default location.  If an action *is* taken on a message (that results in it being saved somewhere; i.e., ‘fileinto’), then the implicit keep is removed (since you have explicitly said where to put it).

So there’s the “keep” keyword (see 4.3 <https://www.rfc-editor.org/rfc/rfc5228#section-4.3>), to “do what you would do in the implicit keep” (more or less).

So:

fileinto :create “ac” -> puts the message into “ac” and removes “implicit keep”
keep -> puts implicit keep back (more or less)

fileinto :copy :create “ac” -> puts a *COPY* of the message into “ac”, and the original retains “implicit keep”.

They do the same thing, though I try and avoid unnecessary extensions when I can.
