First getmail/fetchmail etc. would have to add some custom headers like
But before that can happen getmail/fetchmail need to be able to retrieve
the IMAP flags and add them to a header, finally sieve would need to be
able to remove this header to restore the mail back to its original
If dovecot/pigeonhole could manage the resubmission internally, then you
also have the benefit, that it wouldn't need any extraction/reinsertion
in formats like dbox at all (unless sieve allows changing headers/body).
