Hi,

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
Trash.

I've documented the whole configuration here:

   * https://blog.microlinux.fr/spamassassin-centos/

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
functionality.

Did any of you guys succeed in doing this anyway?

Cheers,

Niki


I've used for quite some time now a combination of
postfix+SA+MailScanner for this, not delivering mails, but letting those
in a quarantine, and using Mailwatch (http frontend) to let people
release mail from the quarantine, etc ..

Thanks, Fabian. I was looking for something like that for long time. I was using the above under amavisd-new. And as I didn't find GUI front-end ;-( I ended up using maia mailguard. By that point I switched servers to FreeBSD, and there is FreeBSD maia port which is being actively maintained by brilliant person, so that may be the best source to get maia from, not the main maia website.

Thanks again, it looks like mailwatch does everything I needed (and found in maia): per user white/blacklists, other individual setting, quarantene release, etc.

And the ansible role that I initially used for this on CentOS 7 :
