Postfix - Relay access denied
 
Hello,

I've configured my box according to the perfect Ubuntu 6.06 setup with ISPConfig installed.

Recently my server have become unresponsive. It answers ping but not web-requests. I'm not sure about the cause but I've found this in my logs related to Postfix. Probably some spammer trying to relay from my box. But can this be causing my problems?

Simply restarting Apache doesn't work. I have to restart the entire box.

Code:
Apr 21 09:37:16 hostname postfix/smtpd[2960]: connect from unknown[218.16.119.142]
Apr 21 09:37:17 hostname postfix/smtpd[2960]: NOQUEUE: reject: RCPT from unknown[218.16.119.142]: 554 <dvdr0503@yahoo.com.cn>: Relay access denied; from=<udzgdskre@yahoo.com> to=<dvdr0503@yahoo.com.cn> p

Are there any errors in Apache's error log?

Open /etc/apache2/apache2.conf and increase the value of MaxClients. Restart Apache afterwards.
