Re: [Dovecot] Using IMAP keywords instead of mailboxes for spam with dovecot-antispam

I haven't looked at your code, but struct mail always has a transaction (mail->transaction). You could fail the transaction by hooking into transaction_commit and calling rollback if your internal failure-flag was set.

But that sounds a bit extreme.

Indeed. But I suppose if I always have a transaction I'll already be hooked into it, I'll check that out.

Aren't you just adding/removing a single keyword? If so, you can use mail_update_keywords() to just add/remove that without reading/touching other keywords.

Evolution for example always replaces the complete keyword list, so that doesn't really work easily.
