Issue : Postfix and PHPMailer

Greetings, Everyone!

I am creating a website for my school and one last thing is missing : website send mail. I am running a beautiful server with the last Virtualmin (on Debian 8) with MySQL, and PHP 7. Everything is working fine : website and emails (both Roundcube and Thunderbird). Just PHPmail is not.

The webiste is running with Joomla 3.6 (support PHP 7) and when I run the test mail (Global Config > Mail Settings) after the proper mail values, the following error message appears: Notice: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting and Error: Test mail could not be sent.

I also have a Mautic intance and when I run the test mail after the proper configuration, the error message appears: Connection to mydomain.tld:143 Timed Out Log data: ++ Starting Swift_SmtpTransport !! Connection to mydomain:143 Timed Out (code: 0) ++ Starting Swift_SmtpTransport !! Connection to espm.life:143 Timed Out (code: 0)

The reason why I think this is related with PHPMailer is because no evidence appears on /var/log/mail.*. The request of the message doesn’t get to Postfix. So I checked php.ini and I realized that sendmail_path = was commented and empty. So, I uncommented it and added first the default sendmail -t -i (as I figured in others topics on internet) then with postfix only. Restarted Apache in both situations and had no success.

I don’t know what I could do. So I am here to hear from you guys.

This is the /etc/postfix/master.cfg :

This is the php.ini: [mail function] sendmail_path = postfix ;mail.force_extra_parameters = mail.add_x_header = On mail.log =/home/mydomain/

This is tail /var/log/mail.log just after the request of test mail on website (nothing related) : Jul 28 11:30:25 host1 postfix/anvil[1248]: statistics: max cache size 1 at Jul 28 08:27:04 Jul 28 11:56:15 host1 postfix/master[25292]: terminating on signal 15 Jul 28 11:56:35 host1 sendmail[4593]: alias database /etc/mail/aliases rebuilt by root Jul 28 11:56:35 host1 sendmail[4593]: /etc/mail/aliases: 3 aliases, longest 4 bytes, 37 bytes total Jul 28 11:56:36 host1 sm-mta[4641]: starting daemon (8.14.4): SMTP+queueing@00:10:00 Jul 28 12:22:26 host1 postfix/master[7231]: fatal: bind 0.0.0.0 port 25: Address already in use Jul 28 12:23:21 host1 postfix/postfix-script[7280]: error: unknown command: '' Jul 28 12:23:21 host1 postfix/postfix-script[7281]: fatal: usage: postfix start (or stop, reload, abort, flush, check, status, set-permissions, upgrade-configuration)

What should I do? Anyone?

Thanks in advance,

Howdy,

Are you able to send email from other tools, such as RoundCube, or a desktop client like Outlook or Thunderbird?

That is, is the problem just with this one application?

Also, what is the output of these commands:

netstat -an | grep :25 netstat -an | grep :143 iptables -L -n
