I have a problem with the email root@localhost not working on centos 3.5 with plesk. This has always worked in the past. Anytime I test my ecommerce store the default email address has been root@localhost and has sent an email to my domain email address when testing. Just recently this has stopped working. The ecommerce store is php. I contacted the ecommerce store developer and root@localhost works for him. This is a reply from plesk about cgi recently on my cgi forms that were working, stopped working, and somehow started working again without anyone finding the problem: >>>>>>>>>>>>> "Actually root@localhost shouldn't work at all. The point is that qmail unlike sendmail is unable to pass messages via the system mail delivery into the /var/spool/mail/username file. It works only via SMTP. Please use an actual mail address in your cgi scripts." >>>>>>>>>>>>>> Since the ecommerce store is php and NOT cgi and root@localhost has been working for months is there someplace I can look to try to find the problem? This is what is listed in /etc/hosts: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost 184.108.40.206 godslove.designhosting.biz godslove Thanks!
