The problem is that people might not have sendmail installed (or
even a program which fakes it, like Postfix does). I would rather
use the PHP function call as the PHP build on the machine will have
been done correctly for that type of system, working around it is
usually a bad idea.<br>
<br>
Also, sendmail is often not present in /usr/lib (that's there for
ancient historical reasons, not appreciated by all modern system
builders).<br>
<br>
So I'm reluctant to call sendmail directly, as that's avoiding all
the (sensible) logic in the PHP configuration script when PHP is
built on that system.<br>
<br>
On true sendmail systems (and not necessarily on other mail systems
that fake the sendmail binary), the Return-Path header will be set
in the sendmail.cf file. The last thing I want is for people to have
to edit their sendmail.cf file, they shouldn't have to do that for
an app which is just trying to send mail and not process it.<br>

<div>Ok,</div>
<div> </div>
<div>I'm not a PHP programmer, but I researched this issue and
found this reported issue as a bug on the PHP Solaris forum back
in 2004.</div>

<div> </div>
<div>I also applied the code presented in the above bug trac and
substituted the logic from the bug trac with the mail() logic
and the Return-Path works (Diff below).</div>
<div> </div>
<div>
<div>I uncompressed the Julian's php rpm package in the Zendto
centos-64 vm and found that the bug was not present in that
package, so the issue appears to be an interaction issue
between sendmail and PHP. Either sendmail is not accepting
the Return-Path or PHP is not providing (or providing
incorrectly) the Return-path to sendmail.</div>
<div> </div>
</div>
<div>I also downloaded the current PHP 5.2 build and grep'd for
the bad code noted in the bug trac that the bug was not present
in that package.</div>
<div> </div>
<div>
<div>Julian,</div>
<div>As usual, I'll defer to you on what you'd like to do as far
as final code changes. I'm just reporting my discoveries for
you.</div>
<div> </div>
<div>
<div>I used Zendto to send an package to a fictitious,
non-existent email account and received a bounce back to my
email account from my MTA with the original Zendto message
attached. Yea!!!</div>

</div>
<div>Below is the diff file for the changes I made that worked,
you previously used a return statement and this does not and my
cause issues.</div>

<div>Please let me know what changes you make to the code.</div>

<div>I was looking at this same issue
yesterday, but ran out of time.</div>
<div> </div>
<div>a snip from the web on the
Return-Path</div>
<div> </div>
<div>Envelope information: Return-Path,
Received<br>
Return-Path<br>
The value of a Return-Path field is
tokenizable. It shows the return path of
the message, i.e., the address that
bounces will be sent to. It is either
(1) a < token followed by a >
token, indicating an empty return path,
or (2) a bracketed address. Two
examples:</div>
<div> </div>
<div> Return-Path: <><br>
Return-Path: <<a
href="mailto:God@heaven.af.mil"
moz-do-not-send="true">God@heaven.af.mil</a>></div>
<div> </div>
<div>Messages transmitted through SMTP
generally do not have Return-Path
fields; the return path is transmitted
out-of-band in the SMTP MAIL request.
When a message is stored in a mailbox,
the return path is stored in a
Return-Path field. If the message is
then retrieved (e.g., through POP) and
sent through another SMTP hop, the
Return-Path is removed and the return
path is again sent out-of-band. </div>
<div> </div>
<div> </div>
<div>I'm pretty sure the function calling
it is in the lib/NSSDropbox file, but
have not figured out exactly how to add
the coding.</div>
<div> </div>
<div>I'll be watching this thread.</div>
