I am currently trying to get Leopard's web sharing/PHP sending email, but I am not sure how to configure PHP's SMTP. Currently when I use PHP's mail() function it seems successful, but I don't actually receive the email. The only reference for setting up the SMTP in the php.ini seems to be for Windows only: Code: [mail function] ; For Win32 only. ;SMTP = localhost ;smtp_port = 25 ; For Win32 only. ;sendmail_from = email@example.com ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). sendmail_path = /usr/sbin/sendmail -t -i How do I configure PHP to use my ISP's SMTP server? Thanks for any help.
