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.
- Code: Select all
/usr/sbin/sendmail -t -i
My SendMail configuration was built using the M4 macro, and my MC script contains the following.
- Code: Select all
divert(-1)
divert(0)dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')dnl
VERSIONID(`$Id: sendmail-procmail.mc,v 1.2 2004/12/07 01:59:31 g2boojum Exp $')dnl
OSTYPE(linux)dnl
DOMAIN(generic)dnl
FEATURE(`smrsh',`/usr/sbin/smrsh')dnl
FEATURE(`local_lmtp',`/usr/sbin/mail.local')dnl
FEATURE(`local_procmail')dnl
FEATURE(access_db)dnl
FEATURE(relay_hosts_only)dnl
define(`SMART_HOST',`post.demon.co.uk')
MAILER(local)dnl
MAILER(smtp)dnl
MAILER(procmail)dnl
Finally, my PHP now contains this.
- Code: Select all
$mail_subject = 'Account activation for '.$url;
$mail_header = 'From: QWeb <'.$qwebs_email.'>'."\n";
$mail_header .= 'Reply-To: QWeb <'.$qwebs_email.'>'."\n";
$mail_header .= 'Return-Path: '.$qwebs_email."\n";
$mail_header .= "X-Mailer: PHP v".phpversion()."\n";
$mail_header .= 'MIME-Version: 1.0'."\n";
$mail_header .= 'Content-Type: text/html; charset="iso-8859-1"'."\n";
$mail_header .= 'Content-Transfer-Encoding: 8bit'."\n";
$mail_body .= '<p>Thank you for registering an account with '.$url.'.</p><p>To activate your new account simply click the following link.</p><p><a href="http://'.$url.'/accounts-'.$activation_code.'.php">http://'.$url.'/accounts-'.$activation_code.'.php</a></p>'."\n\n";
// ini_set('sendmail_path','/usr/sbin/sendmail -t -i -f '.$qwebs_email);
mail($email, $mail_subject, $mail_body, $mail_header);
// ini_restore('sendmail_path');
$page_content .= ' <p>Your account has been created and an activation E-Mail has been sent to the address specified.</p>'."\n";
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.
- Code: Select all

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.
- Code: Select all
X-Authentication-Warning: athlon1200.home: apache set sender to support@*************.com using -f
Thanks.
EDIT:
I've now added apache to the /etc/mail/trusted-users file, and rebuilt my sendmail configuration as follows.
- Code: Select all

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.
- Code: Select all
$mail_subject = 'Account activation for '.$url;
$mail_header = 'From: QWeb <'.$qwebs_email.'>'."\n";
$mail_header .= 'Reply-To: QWeb <'.$qwebs_email.'>'."\n";
$mail_header .= 'Return-Path: QWeb <'.$qwebs_email.'>'."\n";
$mail_header .= "X-Mailer: PHP v".phpversion()."\n";
$mail_header .= 'MIME-Version: 1.0'."\n";
$mail_header .= 'Content-Type: text/html; charset="iso-8859-1"'."\n";
$mail_header .= 'Content-Transfer-Encoding: 8bit'."\n";
$mail_body .= '<p>Thank you for registering an account with '.$url.'.</p><p>To activate your new account simply click the following link.</p><p><a href="http://'.$url.'/accounts-'.$activation_code.'.php">http://'.$url.'/accounts-'.$activation_code.'.php</a></p>'."\n\n";
mail($email, $mail_subject, $mail_body, $mail_header, '-f '.$qwebs_email);
However I still havn't managed to remove the authentication warning Apache is adding to the headers.
Any advice?
Thanks.
