Authentification SMTP failed

hello,
The port 25 is blocked on my server and I change inside the roundcub config by 587.
But on the port 25 or 587 when I try to send an email fom rouncube to gmail I have this error Authentification SMTP failed appear.
Thank you

$config = [];

// Do not set db_dsnw here, use dpkg-reconfigure roundcube-core to configure da>
include_once("/etc/roundcube/debian-db-roundcube.php");

Code:

$config['default_host'] = 'localhost';

// SMTP server host (for sending mails).
// Enter hostname with prefix ssl:// to use Implicit TLS, or use
// prefix tls:// to use STARTTLS.
// Supported replacement variables:
//$config['smtp_server'] = '%h';
$config['smtp_server'] = 'localhost';

// SMTP port. Use 25 for cleartext, 465 for Implicit TLS, or 587 for STARTTLS (>
//$config['smtp_port'] = 25;
$config['smtp_port'] = 587;

// SMTP username (if required) if you use %u as the username Roundcube
// will use the current username for login
$config['smtp_user'] = '%u';

// SMTP password (if required) if you use %p as the password Roundcube
// will use the current user's password for login
$config['smtp_pass'] = '%p';

// provide an URL where a user can get support for this Roundcube installation
// PLEASE DO NOT LINK TO THE ROUNDCUBE.NET WEBSITE HERE!
$config['support_url'] = '';

// Name your service. This is displayed on the login screen and in the window t>
$config['product_name'] = 'Roundcube Webmail';

// This key is used to encrypt the users imap password which is stored
// in the session record. For the default cipher method it must be
// exactly 24 characters long.
// YOUR KEY MUST BE DIFFERENT THAN THE SAMPLE VALUE FOR SECURITY REASONS
$config['des_key'] = 'xxxxxxxxxxxxxxxxxxxxxxx';

 

any chance your hosting provider of choise happens to be hetzner.com?
They block port 25 and 587 until you've been a customer for about a month / payed your first bill.
You can request unblocking at the limits page on your cloud console ; if you need it on dedicated servers, you'd need to request there aswell.

 

no I am at ovh.com ,you can test on this link clicshopping.org
It vps

 

yeah, I went to sleep after my post, should have done 5 minutes before.

looking fine except for the missing correct reverse dns setting for your ip => make sure it maches, see attached screen
where to edit your ips reverse dns name.

 

@til,
tk,
I reconfigure the smtp on port 25. It does not work
As a side note, most cloud providers block port 25 today, so it's not just Hetzner but also AWS and likely OVH too. ==> In this case we must to set smtp port on 587 for example inside the rouncube ?


@ztk.me
About Networks tools, it's correct

About the port


maybe there is a problem with the firewall ?



Note: I can receive an email from google, yahoo.fr. My problem is just to sent an email.

A last image



Thank you

 

there response, connexion refused

 

Milter service seems not available. That is Mail Filter.
Is some service not running?

Code:

systemctl --state=failed

Is system using rspamd or amavis?

Code:

systemctl status rspamd.service 

 

thank you
about memory : 4go
usage is around 40%

service rspamd start

That's not good !

 

regarding your smtp banner, might be aswell that /etc/hostname only contains sub part of your full hostname.
e.G. it contains "vps". Just checked a few ispconfig installations and they all have $hostname in their banner config.
So I suspect your /etc/hostname does not and usually need not contain the fqdn, /etc/mailname was used for that
anyway long story short;
check your /etc/postfix/main.cf
smtpd_banner

should be at the top, you can remove $myhostname and set it to vps.clicshopping.eu

assuming this is the correct hostname, set as reverse dns and used internally.

 

hmm
could you try

Code:

apt update
apt install -f
systemctl daemon-reload
systemctl enable rspamd
systemctl enable clamav-daemon

 

@ztk.m, Thanky you for your recommendation

nano /etc/hostname
Here do I need todo somethig ?

nano /etc/postfix/main.cf
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

HereI change $myhostname by vps.clicshopping.eu


Just above
apt update
apt install -f

clamav-daemon seems ok

 

my bad, sorry I forgot the two lines

Code:

systemctl unmask rspamd
systemctl unmask clamav-daemon

edit: and after this the enable + start commands

yes, main.cf
smtpd_banner = vps.clicshopping.eu ESMTP
should be fine


if the services do not start after this

Code:

journalctl -xeu clamav-daemon
journalctl -xeu rspamd

not sure top of my head if it's available on ispconfig

 

I insert that :

#smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_banner = vps.clicshopping.eu ESMTP $mail_name (Ubuntu)
/etx/init.d/postfix restart ==> ok

systemctl umask rspamd

seems fine !

 

Hah you figured I made a typo and misspelled unmask

Also edited my post in regards of rerunning systemctl enable / start / status
afterwards.

 

yes I know

But I can not sent email to rouncube to gmail for example. I have always the same message
There the result after a reboot
