Having a little trouble with my server recently. I'm currently int he process of launching a second business venture and need to get my servers running properly. Until now my SMTP server, SendMail, has been configured only for web based contact forms and internal SMTP services. However my new membership system requires users to authenticate via E-Mail. In developing this system it has come to my attention that some POP services filter my generated E-Mails as spam, and in checking the headers of these E-Mails I wasn't entirely surprised.
I've spent all day reconfiguring both my PHP and SendMail services, rewriting scripts, and stressfully picking off the scab I once had.
Result? My headers are now mostly correct, yet my E-Mails appear to be blocked by all but a very poorly configured Hotmail account.
First off my PHP configuration now only sets the path variable, and doesn't use the -f parameter.
My SendMail configuration was built using the M4 macro, and my MC script contains the following.
Finally, my PHP now contains this.
Note the ini_set and ini_restore functions appear to have no effect, maybe thats a Windows function only? I've commented them out for now.
When I attempt to send out mail now, the server logs something like the following.
However The only time I actually recieve a message is if I send to a badly configured Hotmail account that doesn't reject anything. At which point my headers look fine, though I'm not sure why the Return-Path header is being set to apache@athlon1200.home.
Any idea what I'm missing?
Thanks.
EDIT:
If I explicitly declare an E-Mail address in php.ini the E-Mail appears to be accepted by most POP servers, however since this configuration is global the server will then force all outgoing E-Mails sent from hosted sites to be given incorrect from addresses. The ideal solution would be the PHP ini_set() function, but this appears to be ignored on my Gentoo GNU/Linux system running Apache 2 and PHP 5. Am I missing a configuration setting? Whats more, use of the -f parameter implants an authentication warning in the headers, which could be used by some POP servers for spam filtering.
Thanks.
EDIT:
I've now added apache to the /etc/mail/trusted-users file, and rebuilt my sendmail configuration as follows.
The X-Authentication-Warning header still appears though, even after restarting the SendMail daemon.
Any advice?
Thanks.
EDIT:
Finally got it sending (somewhat slowly - I guess because its relaying rather than sending direct) without the need for a statically defined sender address in php.ini, with the following PHP.
However I still havn't managed to remove the authentication warning Apache is adding to the headers.
Any advice?
Thanks.
