Headers can easily be added at smtp-time in acl's, or at delivery-time in
router/transport sets.

Ordinarily not much need for Seive or filters for that.

As far as having Dovecot index the messages as already read, you might send them
to a folder named 'Read'.

;-)

Otherwise, I suspect you will be 'fighting' Dovecot's indexing system, even if
you deliver them to, for example:

~/<wherever>/Maildir/cur

We deliver to bepoke folders, and Dovecot is au fait with that, but we let the
MUA worry about the read/unread status (Moz mail message filter rules, etc.).
