moving mail to another maildir based on tags and renaming files

[erik colson <eco@ecocode.net>]

Hi,

I would like to move mails selected by a notmuch query
(i.e. "tag:movethismailtobox-ThisBox") to *ThisBox*
I need this to somewhat still have usable access through my phone IMAP
client.

I am actually using afew already, but as I have 1000+ mailboxes it is
unmaintainable to create the rules manually.

So I am thinking to either modify the afew-configuration file with
another script (=not nice) or either write a script myself.

It wouldn't be very difficult to generate the necessary
  notmuch search --output=files ... | xargs mv ...
  
but, there is a catch: I use isync to synchronize my mails with my IMAP
server and therefor I must rename every message file when moving it.  As
I am not enough aware of maildir and IMAP servers, I am pretty ignorant
to what the new filename should be.

So I wanted to check if somebody else already wrote some
bash/perl/whatever script which handles this ?

thx
