RedHat 9, using sendmail 8.9 and PHP 4.2.2
Certain ISPs are rejecting emails which have originated from a PHP form on my server. Sample bounced mail:
The original message was received at Thu, 19 Feb 2004 10:54:49 GMT
from orca [127.0.0.1]
----- The following addresses had permanent fatal errors -----
<user's email address@user's domain.com>
(reason: 550 rejected: cannot route to sender <firstname.lastname@example.org>)
----- Transcript of session follows -----
... while talking to mx01.schlund.de.:
<<< 550 rejected: cannot route to sender <email@example.com>
554 5.0.0 Service unavailable
I'm at a loss as to what I've mis-configured. My various files are:
[root@orca MailingList]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 orca localhost.localdomain localhost
[root@orca MailingList]# cat /etc/resolv.conf
[root@orca MailingList]# cat /etc/sysconfig/network
Sendmail Local Domains table (via webmin)
apache httpd.conf (selected line)
Within PHP I'm setting the FROM address to my own emal address, but somehow the firstname.lastname@example.org
ldomain is slipping through.
Can anyone suggest what I'm doing wrong? I'm stumped on this, and I'm "all googled out" trying to find the answer.
