I receive emails but cannot send them: authentication failed

[Yves89000]

hello 

Emails aren't really my thing to install on the server.

My mail server is working. Squirremail works without problem (sending and receiving mail).

On the other hand for Roundcube the reception of emails works, but not the sending.

I keep getting errors smtp() error: Authentication failed.

When I send emails with squirremail, it happens:

On the other hand if I send with roundcube it does not pass:

I don't have any other logs showing up.


Do you have an idea ?

     Here is my Roundcube config:

Code Select Expand


     // IMAP host chosen to perform the log-in.
     // See defaults.inc.php for the option description.
     $config['imap_host'] = 'localhost:143';
     // SMTP server host (for sending mails).
     // See defaults.inc.php for the option description.
     $config['smtp_host'] = 'localhost:25';
     $config['smtp_auth_type'] = 'PLAIN';


I use the version 1.6.1

squirremail seems well configured on localhost:25 (checked via /usr/share/squirrelmail/configure)


If someone could help me that would be great

"Authentication failed." is a clear message so check the smtp auth settings. The defaults are:

Code Select Expand


// 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';

If you would like to disable smtp auth then set the options to empty strings.

 $config['smtp_host'] = 'tls://localhost:25';

also, usually submission port is 587, not 25.
