Issue Mail not deliverd when sent locally

[Schoelje]

I have an odd issue with my mail server.

On the server I checked whether the mail server was running:

sudo netstat -ntap | grep 25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1088/master

sudo telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 my_domain.nl ESMTP Postfix (Debian/GNU)

So, that looks okay.

I can use my SMTP server from my home and even on the server from the command line:

echo -e "From: [email protected]\nTo: [email protected]\nSubject: sendmail test\n\nThis is the body,\nwith multiple lines." | sendmail -t

However, when I try to send a test mail from Plone, the log files indicate that the message is sent. However, I never receive the message. There are no errors in /var/log/mail.err

This is the /var/log/maillog file:

The queue is empty and this line tells me that the message was sent:
Apr 12 14:11:54 h2776529 postfix/pipe[6335]: 9B7E81C3A1F3D: to=<[email protected]>, relay=plesk_virtual, delay=0.18, delays=0.09/0.01/0/0.08, dsn=2.0.0, status=sent (delivered via plesk_virtual service)

All seems to be alright, but still, I don't receive that message.

I've disabled the firewall and I do not use a spam filter.

The correct IP addresses are in the "Trusted IP addresses" list and no IP addresses are banned in Fail2Ban.

Using an external SMTP server results in the same: message is sent, but is not received. So, what is holding the messages back if sent from Plone?

Any ideas?

Is Plone able to send to an outside email address?

 

[Schoelje]

I think there's something wrong in Plone, not the server configuration:

• Cron jobs deliver reports to the correct address.
• This morning I received a "Package Update Manager notification" from Plesk.
• I've recreated the web forms in Plone with a minimum of configuration and they now function.
• From Plone I cannot send a test email to test the SMTP server settings.

I don’t understand why it doesn’t function but it has no consequence for what I need: I can send and receive e-mails on the new domain and the web form is functioning as expected.

Thanks for your help!
