[Dovecot] After-delivery sieve processing

[Daniel L. Miller]

Is it possible to run sieve against an existing mailbox?

My application: I've got a mailbox that stores status messages from 
multiple sites.  It's easier to check up on recent events by having them 
all in one folder.  However, after I've read them, I'd like to have them 
archived to individual folders per site.  I currently have a sieve 
script that uses "fileinto" to sort the mails - but I'm thinking of 
removing it from deliver if I can run it as a manual job later.

I suppose another method would be to duplicate the mails on delivery 
into both the main folder and the per site folders, then delete after 
I've read them - but for whatever reason that strikes me as inelegant.
