Not if the mail is never accepted. I reject mail marked that
way with a "550 Already marked as spam" from Postfix (using header
rules - so a quoted mail message won't trigger it). There are plenty
of large institutions and sites "kind enough" to mark outgoing mail
as spam, but send it to you anyway (mostly government or educational
sites).
