Scalix Forums

Hi, I installed Scalix with Spamassassin and Spamass-milter on CentOS 5.0.
I did the installation as what manual says.Everything works fine except the receiving part. I do receive mails and block some spam mails.
Some suggested spam mails were put into spam folder.

Problem 1:
I did a redirect for all my emails.

The problem is in the received emails, some detected as spam mail can not be sent out.
and information is given as:

because: A mail transport failure occurred
550 5.7.1 Blocked by SpamAssassin

For example, I got 10 mails from outside. 5 are still spam mails. The spam mails are not blocked, but when they were redirected
to other mailbox, they were stopped by spamassassin. I think my spamassassin is not working when receiving emails, otherwise,
it will stop these spammails coming in.

Actually, I have already set up my smtpd.cfg file with spamassassin. In this file, I got
SMTPFILTER=TRUE
INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run//spamass.sock, F=, T=C:15m;S:4m;R:4m;E:10m')

What should I do to active spamassassin in receiving emails?


Problem 2:
This is not about Scalix system. It is about hacking our machines.
I checked the log and found someone is testing our mail server by sending a lot of emails to our server's invalid email address.
It is like they tried all possible email name combinations with *@company.com. These addresses do not exist.

Any one can help with block such attacks?


Thanks

Anyone can help me?

Thanks.

1. first problem fixed. the stmpd file just take action line by line. I changed the order and it works.

2. still no idea about how to stop people trying different id on my email server.

3. New problem. how can I stop people from outside sending mails to mailer-daemon@company.com
And my administrator user still get such reply:

Message could not be delivered to the following recipient:

mailer-daemon@

because: A mail transport failure occurred
