In IMAP storage messages are immutable, per spec. That means: You cannot transparently change the content of a message, e.g. add/remove headers or (parts of) the body, once the message has been delivered.
If you do it the IMAP way, each manipulated messages (I mean the content, not the keywords/tags/flags) becomes a new message, hence, the clients might download it again.
If you keep that in mind, you can successfully manipulate the content of messages in Maildir by:
- rename message somewhere else,
- manipulate it
- rename it to maildir_mailbox/tmp
- adjust access permissions
- rename it to maildir_mailbox/new or ../cur making sure the file gets a new filename stem (part of filename before the
colon) than it had originally.
If a new file pops up in cur/new, Dovecot assumes a non-Dovecot delivery and re-indexes the file next time the user accesses the mailbox.
To manipulate the flags I would use PREAUTH.
You can savly remove files from a Maildir.
