Does the plugin change the mbox file directly? > imap(x1234567): Error: Cached message size larger than expected (6796 > 2844) This looks like it does. Existing emails must not be changed, IMAP protocol forbids it (and Dovecot internals don't support it either). The only safe way to drop attachments is to assign a new UID for the mail, which basically means saving a new message without attachments and deleting the old one. The Content-Length header doesn't really have anything to do with this error.
