tips for fighting spams discussion

[kfliong]

Hi,

I got this tips from MailWatch forum. I think that this is a splendid tips
that most of the veteran might already know. But for newbies like me, it's
quite interesting. Anyway, it's posted by Julian (not sure if it's the same
MS julian) and I have some questions about it.

Here is the method posted to help fight spams that got through mailscanner
and went to the user.
---------
Here's how I do it:
1. Choose an e-mail address for recalling the missed spam on the
MailScanner server (ie,
<mailto:spam at mailscanner.mydomain.com>spam at mailscanner.mydomain.com)
2. Add "To:
<mailto:spam at mailscanner.mydomain.com>spam at mailscanner.mydomain.com yes" to
"Is Definitely Spam" rules pointed to.
3. Add an aliases "spam: /dev/null" on the MailScanner server. The mail
will go to bitbucket if released by mistake.
4. Tell the user to redirect the mail to the e-mail address. It should be
blacklisted and be quarantined.
5. Exam the mail and learn the message as spam in MailWatch if needed.
---------

Here are my questions:

1) does the "is definitely spam" feature tied to sa-learn therefore making
mailscanner learn that this is spam or it uses other method to identify the
spam? Or how exactly does "is definitely spam" works?

2) Said in step (3) to point the messages to null. So  it means the
messages will be filtered before it goes to null?

3) In step (4) the users will be able to point all spams that they receive
to "spam at domain.com" and therefore lifting the workload from email admins
but as I understand, forwarding mails will add a ">" in front of the
messages and doesn't sa-learn have problems learning these messages?

Thanks in advance.
