Hello,
Server have 2 IPs.
How it is possible to use one IP for postfix, second IP for php mail (thorugh postfix-sendmail-wrapper)?
Not all php scripts can be configured to use SMTP authorization.
If some website have malicious code then that website can send spam messages through php mail function.
It's okay to blacklist IP address for php mail but not for authorized addressess.
