[CentOS] Spamassassin + Postfix : delete spam mail on the server ?

My mail server is running on CentOS 7 with Postfix, Dovecot and
Spamassassin. I get quite a lot of spam on a few accounts, and
Spamassassin does its job fine. Spam mail is identified correctly, and
it looks like there are no false positives, e. g. valid mail is never
identified as spam.

When a message is flagged as spam, the subject line is rewritten to
begin with [SPAM]. Then, a filter in Mozilla Thunderbird is setup, and
when a subject line begins with [SPAM] the message is directly sent to

I've documented the whole configuration here:

The problem with this setup is that spam mail is still delivered, and I
need Thunderbird's filters to weed out incoming mail. And when I'm using
my webmail (running SquirrelMail), my inbox is a tsunami of unread
[SPAM] messages.

So I'd like to go a step further and delete all messages flagged [SPAM]
directly on the server. It doesn't look like Spamassassin provides this

Did any of you guys succeed in doing this anyway?
