If the -annotate switch is given, the message being replied-to will be

Also, see anno(1).
IMAP has a notion of message flags:

One can set \Answered flag on the message via IMAP.
Mail clients may set their own flags, as there are some standardized.
UW imapd suite maintains flags by having an invisible message at the
beginning of the mbox folder. I think some IMAP servers maintain
"Status:" header in the message.
