Title: SMTP Error (550)
Post by: madmax87 on July 15, 2011, 07:06:48 AM
Hi I'm new to Roundcube and recently installed it and followed the set up, added the pop.domain.com and smtp.domain.com as requested and the information claimed to be correct, I tried a test email (sending) but it failed and after I logged in and tried to send a normal email i got the following when pressing the send button?

SMTP Error (550): Failed to set sender
"[email protected]" (bosauthsmtp01: Host
00.00.000.00: No unauthenticated relaying permitted)

Can anyone help explain what's caused this error and how it can be resolved please?

Thanks loads!

Looks like the SMTP-server does not accept the authentication. Just check the ./config/main.inc.php for the following options:


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

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

// SMTP AUTH type (DIGEST-MD5, CRAM-MD5, LOGIN, PLAIN or empty to use
// best server supported one)
$rcmail_config['smtp_auth_type'] = '';

Yeah I've got that

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

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

// SMTP AUTH type (DIGEST-MD5, CRAM-MD5, LOGIN, PLAIN or empty to use
// best server supported one)
$rcmail_config['smtp_auth_type'] = '';

So where do I go from there?

I think you need to enable tls/ssl in smtp_server option.

Since the error state 'No unauthenticated relaying permitted' you'll probably need to add a smtp username and password to authenticate.
