After upgrading ISPConfig from 3.0.3 to 3.0.4, the server (Debian Lenny 5) can't send or receive emails : Server error: '451 4.3.5 Server configuration error' .
In the mail warnings of ISPConfig, I have several entries like this : postfix/smtpd[17211]: warning: unknown smtpd restriction: "permitsmtpd_client_message_rate_limit"
How can I solve that please ?

I solved my problem by commenting "permitsmtpd_client_message_rate_limit = 100" for "smtpd_helo_restrictions" in /etc/postfix/
