I looked for mail(); that was obviously the first thing I did, but I did not find it in the install script.
The installer calls other files and so on, that's why I am looking for a trace utility or something that avoids having to scan all the files.
I'd try a "grep" but that does not tell me if the mail() it finds is triggered down from the installer.
Are there any other calls than mail() that can send an e-mail?
The author seems to have hidden the call so it is not quite so obvious to find but I know it is there. If there was a trace utility I could get to the exact line that trips the firewall which tells me that Apache is trying to send an e-mail when I run the installer.
