intresting sendmail, php.ini problem

[blaci]

Hi!

I have Rad Hat Linux 7.2, an internal HSP56 MR modem (56kbits/s) . I connect to the Internet using dial-up.
I want to send e-mails with php ( mail() function ) from my 'server' (localhost) .

I have the sendmail server at /usr/sbin/sendmail BUT even if i change in the php.ini the smtp_path to /usr/sbin/sendmail, the mail() function doesn't send e-mails...

What should i do??

Thanks for your answer!
