And further, if the spam goes into the recipient mailbox, then the
recipient receives the spam. So there is no point bothering running a
spam filter at all as all spams go where spammers want them to go.
A spam filter that only adds a tag like [SPAM_SUSPECT] to the subject of
the mails is useless, and worse it delays mails a bit and waste
resources. It can even cause mail loss as most users will just create a
rule to delete all mails containing the tag, and no one (sender or
recipient) is warned that a mail failed to be delivered.
