Re: What's the difference between "UNKEYWORD \Seen" and "UNSEEN"?

keywords are a specific type of flag. As defined by the RFC:

A keyword is defined by the server implementation. Keywords do not begin with "\".

My interpretation is that for searching for \Seen or \Unseen you should use the SEEN or UNSEEN search criteria and not the KEYWORD or UNKEYWORD criteria.

Hi John,

This piece of information was missing for me; that explains it, thank you!
