On my home Fedora Core 4 box I run Apache 2.0. Sometimes when sending mail (with php) no mail is delivered, and 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 apache-home@xxxxxxxxxxxxxx But I still get he error! I did restart apache and went so far as to reboot the machine. WHen gives? Thank you. Dotan Cohen http://technology-sleuth.com/question/what_are_the_advantages_of_lcd_monitors.html qwc
