How to remove attachments from many mails on Cyrus-IMAP Store?

[Bron Gondwana]

Hi Walter,

The only way to remove attachments is to replace the message with an
edited copy of the message.  You can't alter emails in an IMAP mailstore
once they are delivered.
At FastMail we're using the attached Perl module to strip attachments
from emails for our "remove attachments" feature.  It's not pretty, but
it gets the job done.  It needs to be hooked up to some code that
actually connects via IMAP and does the work.
Cheers,

Bron.
