sendmail and qmail both run on the same server. How can I know the which one is used to send email ?
I have a PHP application that sends email via the mail() function. The SMTP server it uses has both process running.
It is a server used for live applications, so I can't stop one process to do some tests.

I'd make sure that the machine really is as you describe. It's possible to get confused about these things, especially as most Unix/Linux MTSes have asendmail
program image file that is nothing whatsoever to do with the Sendmail software package. There's almost never a need to set up a system in this way with two different MTS softwares running in parallel. (Multiple instances of one package is as exotic a configuration as things normally get.)

You will have to look in your php.ini
file, under [mail function]
. Here, the path to the mail sending binary is specified. Whatever is specified here, the mail()
function in PHP will use.
sendmail_path = /usr/sbin/sendmail -t -i
The above one should be the default. So, if you haven't changed anything, PHP will use sendmail
.
As @JdeBP mentions, you can also take a quick look at the headers of the mails received. If you look under the various Received
sections, you will find some identification of the server software being used.
Some systems havesendmail
as a symlink to the actual binary provided by the MTA, e.g.sendmail.sendmail
orsendmail.qmail
.

+1. The suggestion in the PHP manual is to pointsendmail_path
directly atqmail_inject
, which will be directly indicative with no further research. But in the general case finding out whose binarysendmail_path
is pointing to is the right answer for PHP on Unix/Linux.

While you're at it, you could mention in your answer that theReceived:
header fields in the received messages will yield very strong clues as to which software, Sendmail or qmail, processed the mail. Sendmail and qmail write trace information in different forms.
