1) install phpmailer on server for various sites, for submit forms, to send mail through the mail server (which is a different machine).
2) how do I set the php error log file to be /var/log/php.log.
3) how to permanently block IP addresses from accessing the server or any web site on the server. This means IP blocking within apache. (I currently have fail2ban installed.)
4) how to change the apache logs for a specific domain to log minimal information.
5) rotate apache web site logs for a specific domain over a 7 day period (for a high traffic site. the logs become too big even with minimal logging so they need to be rotated and overwrite every 7 days).
