Yes, this fixed worked for me as well.

Where can I find this files?

You can find it in roundcube config directory. For example in Centos its in /var/www/html/roundcube/config & in Ubuntu its in /var/www/roundcube/config.

Thanks for this, fixed it for me too 🙂

Thanks a lot, fixed it for me,

Many thanks it work for me too

thanks, it works!!

This trick doesn’ work if: smtpd_tls_auth_only = yes

I changed: // SMTP server host (for sending mails). // To use SSL/TLS connection, enter hostname with prefix ssl:// or tls:// //$config[‘smtp_server’] = ‘localhost’; $config[‘smtp_server’] = ‘tls://localhost’;

// SMTP port (default is 25; use 587 for STARTTLS or 465 for the // deprecated SSL over SMTP (aka SMTPS)) //$config[‘smtp_port’] = 25; $config[‘smtp_port’] = 587;

Now everything works fine.

Nevertheless this blog gave me the hint to look in the right place, so thanks!

Recently while trying to install roundcube I am stuck with the error “roundcube SMTP Error (250): Authentication failed”.

With the error the clear hint is there should be some issue with SMTP setting, so I checked all SMTP settings and I had bit doubt on following settings.

After doing some experiments with my main.inc.php file following tweaks are worked for me.

Linux roundcube ошибка авторизации 250

Ошибка возникает при попытке отправки сообщения

При настройке указал в default.inc.php

$config[‘smtp_auth_type’] = ‘LOGIN PLAIN’;

Если поставить $config[‘smtp_auth_type’] = null;
