dovecot - Apr 2013 - thunderbird detach attachment

Hi all,

Thunderbird has an option to detach attachments from (for example) sent 
items. I've tried it, and it does not work, and also in the dovecot logs 
I don't see anything interesting meanwhile.

Before looking deeper into this: Does anyone here know if this option is 
known to work, or not?

We're running dovecot 2.1.7 on debian wheezy.

Removing unwanted attachments is a nice way to keep mail archives smaller...

Thanks,
MJ

My Understanding of that is
as long as you have your mail folder option offline synchronzied , which
is default at Thunderbird , all actions happens first to Thunderbird
local tmp store , then synced to the server

use secure way ,move all mails in imap sent folder to real local folder
on your machine , then cut attachments , move it back to imap sent folder

at last i guess your problem is not server related anyway, but
Thunderbird might crash mail at trying cut direct on imap folder, i ve
seen this some time before

This looks to work on my 17.0.5 Thunderbird on CentOS 6.4
(I guess Dovecot is not involved but running on 2.2.beta1).
It does detach the file, places it in the chosen folder, removes the 
option to detach or delete from the message menu
but (nice indeed) remembers where you put the attachment and can still 
show it if you click on it or save it again if you want to!!

But how do we know its been detached if it still shows in Thunderbird?
Looking into the actual message file I see the following at the end:

--------------020104000205010901050407
Content-Type: application/vnd.oasis.opendocument.text;
  name="=?UTF-8?B?MjAxMzA0MDQtzpPOoy5vZHQ=?="
Content-Disposition: attachment; filename="20130404-??.odt"
X-Mozilla-External-Attachment-URL: 
file:///LocalData/tmp/20130404-%CE%93%CE%A3.odt
X-Mozilla-Altered: AttachmentDetached; date="Wed Apr 10 12:51:00 2013"

You deleted an attachment from this message. The original MIME headers 
for the attachment were:
Content-Type: application/vnd.oasis.opendocument.text;
  name="=?UTF-8?B?MjAxMzA0MDQtzpPOoy5vZHQ=?="
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
  filename*=UTF-8''%32%30%31%33%30%34%30%34%2D%CE%93%CE%A3%2E%6F%64%74
