Indeed. Maybe my question was not clear, what I'm asking is a way to add
the header to the specific messages via a sieve rule.  I can add headers
via sieve but I don't know if there is a way to get the current time or
to set an header with information from another.

The default behavior of the clients I'm using is to use the time at
which the message has been retrieved from the IMAP server, which does
not really make sense to me.

I don't know what smokeping is.
