New Comment:
I'll give that a try, though this is on a very heavy
loaded production machine (hundreds of web hits per
minute) -- I'll need to wait for the load to settle a
little, hopefully later tonight.
That said, in the meantime I thought I'd share some more
insight testing. I fully replaced sendmail with qmail
to make sure it wasn't something particular with the
configuration of sendmail. Again, the machine has no
problems sending e-mail on the command line or with mail
clients, but mod_php5 hangs on the mail() call.
Curiously enough, before installing qmail if I made the
clientmqueue dir unreadable so that sendmail reported an
error/failure, the mail() call does return immediately
(reporting a failure return code) so the hanging does
seem to be specific to when the mail 'should' go through
correctly.

Please try to reproduce it with only one Apache process (httpd -X) and
if yes - get a GDB backtrace of the place where it freezes.

When I attempt to use the sendmail binary directly, I
have no problems:
$ /usr/local/sbin/sendmail -t -i -v -X /tmp/sendmail.log
[EMAIL PROTECTED]
To: [EMAIL PROTECTED]
From: [EMAIL PROTECTED]
Subject: this is a test...
testing.
[CTRL-d]
The message is successfully delivered both with and
without the above shown header provided. Looking at the
-X debug logs, the difference running the command
directly versus what I'm seeing when php runs is a lack
of the EOF, shown below as follows:
>From PHP:
70503 <<< To: [EMAIL PROTECTED]
70503 <<< Subject: Hi!
70503 <<<
70503 <<< Hi,
70503 <<<
76330 <<< To: [EMAIL PROTECTED]
76330 <<< Subject: Hi!
76330 <<<
76330 <<< Hi,
76330 <<<
76330 <<< How are you?
(Notice the lack of an EOF, it hangs)
Directly on the command line:
40466 <<< From: [EMAIL PROTECTED]
40466 <<< To: [EMAIL PROTECTED]
40466 <<< Subject: testing
40466 <<<
40466 <<< testing2
40466 <<< [EOF]
40466 >>> [EMAIL PROTECTED] Connecting to
[127.0.0.1] via relay...
40466 === CONNECT [127.0.0.1]

I suspect it has nothing to do with PHP and everything to do
with the sendmail binary. It maybe hanging waiting for data,
try to test the sendmail binary to see if it can be used to
send e-mail.

Description:
------------
Using a default install of mod_php5 on FreeBSD, installed
via an up-to-date ports, web pages calling mail() hang
indefintely. This ends up hanging the associated apache
process until it is manually killed. I can send mail fine
from mail clients on the host, from mod_perl, by telnetting
to port 25, just apparently not from mod_php5.
I've tested using the default php.ini mail settings as well
as setting sendmail_path explicitly with different debug
options (e.g. /usr/local/sbin/sendmail -t -i -v -X /tmp/
sendmail.log). Sendmail does log that a connection is
established and the e-mail is written to the log, but it
never closes the connection and only aborts when apache is
killed.
This bug seems very familiar with php bug 22947 yet I'm not
on Windows so perhaps just coincidence.
Reproduce code:
---------------
<?php
$to = "[EMAIL PROTECTED]";
$subject = "Hi!";
$body = "Hello?";
echo("<p>sending mail</p>");
if (mail($to, $subject, $body)) {
echo("<p>Message successfully sent!</p>");
} else {
echo("<p>Message delivery failed...</p>");
}
?>
