How does one mark all messages as read (imap4flag "seen") with sieve?

I had the afterthought that perhaps the problem is that my Antispam
plugin pipe-script simply writes the original message to the filesystem.
It doesn't use dovecot-lda, so the Sieve filters are not being applied.

I would use dovecot-lda if it didn't sefault with my pipe script. :(

Will just have to live with making messages read manually, I suppose!
