On my home Fedora Core 4 box I run Apache 2.0. Sometimes when I try to send mail through php nothing is delivered, but I find this in the logs: <<< 550-Verification failed for <apache@xxxxxxxxxxxxxxxxxxxxx> <<< 550-unrouteable mail domain "localhost.localdomain" <<< 550 Sender verify failed So I changed the only email address in httpd.conf to: ServerAdmin php@xxxxxxxxxxxxxx But I still get the error and no mail is delivered. I restarted apache of course, and when that didn't help, I rebooted the machine- nothing... What must I configure, and how? Php? Sendmail? Apache? Thank you in advance.
