Problems on my Magicspam

[m0rpheu5]

Hello guys, my magic spam stop to work today on 12:00:00, i restarted the server, i reinstall the magicspam, and nothing changes, i´m receiving and send email normally, but the last log in /var/log/magicspam/mslog is:

2010-06-25 11:59:58 magicspam-postfix[7011]: HAM: mua=0,ip=[200.139.115.227:(null)],helo=<eco07.econet-editora.com.br>,from=<treinamento@econet-editora.com.br>,rcpt=<marcelo@contactusconsultoria.com.br>
2010-06-25 11:59:58 magicspam-postfix[7018]: SPAM[check_ip_reverse_dns]: mua=0,ip=[213.154.6.224:(null)],helo=<buukaju>,from=<maudbettinabq@gasworks.com>,rcpt=<janio@itaf.com.br>
2010-06-25 12:00:00 magicspam-postfix[7030]: SPAM[check_ip_reverse_dns]: mua=0,ip=[213.154.6.224:(null)],helo=<buukaju>,from=<maudbettinabq@gasworks.com>,rcpt=<consultoria@itaf.com.br>

my license in the magicspam by plesk appear that:
Expires: 07-20-2010 Next Update: 07-17-2010

so i think that the problem isn´t on the license, in the postfix there is no error, so what could be?

in t he /etc/postfix/main.cf i have this:
smtpd_recipient_restrictions = permit_mynetworks, check_client_access pcre:/var/spool/postfix/plesk/no_relay.re, permit_sasl_authenticated, reject_unauth_destination,check_policy_service unix:private/magicspam

so i think that is everything right, in the other server that i have magicspam everything is working fine

Help me guys, i´m receiving a lot of spam now

Please provide some additional information to give us a better idea of your setup:
1) Operating system and version (and 32 or 64-bit)
2) MagicSpam version
3) Plesk version

In the mean time, please try the following:
1) Enable/disable the plugin and note any unusual output
2) Verify that you are using the latest version of MagicSpam
3) Determine the size of the log file. We have seen instances in the past where the log file has grown to an excessive size (more than the file system is capable of handling in a single file) which interferes with the operation of MagicSpam.
