[Dovecot] 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
