Your own mails to a (simple) mailinglist, given that you'll likely already have a copy in your "Sent" folder as the on-list version comes back to you? Received mail matching several topics at once, and the user first copies it to archive folder A, then moves the original to folder B, all via IMAP? Versions of an e-mail that are *marked* deleted, but not yet expunged, and can still be seen/accessed/undeleted/moved/copied/... in *some* IMAP clients?

Re: Obtaining the IMAP GUID from a sieve script
Just for the record, it turns out that doveadm is the key to happiness here. It lets me find and manipulate messages by message-id (or any other header) which is what I needed. rg

But there’s another reason I want the Dovecot UID: I want to be able to find the file in a user’s maildir corresponding to a particular message that passed through sieve so I can do forensic analysis in the event that the spam filter isn’t doing the right thing. rg

Re: Obtaining the IMAP GUID from a sieve script
Because not every email has one. RFC5322 doesn’t require them.

Obtaining the IMAP GUID from a sieve script
Is there any way to obtain the IMAP GUiD of a message that is being processed by a sieve script? I’m writing a filter that needs to to keep track of message identities as they are moved around between folders. I could add my own id header, but I’d rather not have to reinvent that wheel. Thanks, rg
