FWIW, MailTags accomplishes this by adding a X-MailTag-*** header to the 
message, containing the date in JSON-formatted notation.  This is 
usually preserved by the server, making it visible to multiple clients.  
I suppose IMAP keywords could also be used, but MailTags chose not to 
use that for any of its implementation (even its tags don't use IMAP 
tags).
