I have set up postfix to use port 587 because I don't want to use 25.
I have changed "$rcmail_config['smtp_port'] = 587;" in main.inc.php and in /etc/postfix/master.cf enabled "submission" and disables smtp.
When I try to send from roundcube I get "SMTP Error (250): Authentication failed."
Any ideas?

Re: SMTP Authentication failed

If I leave "smtp_user" and "smtp_pass" blank in main.inc.php I get "530 5.7.0 Must issue a STARTTLS command first".

Re: SMTP Authentication failed

Did you check "smtp_server" parameter in Roundcube config file (main.inc.php)?

// SMTP server host (for sending mails).                                           
// To use SSL/TLS connection, enter hostname with prefix ssl:// or tls://         
// If left blank, the PHP mail() function is used                                 
// Supported replacement variables:                                               
// %h - user's IMAP hostname                                                       
// %n - hostname ($_SERVER['SERVER_NAME'])                                         
// %t - hostname without the first part                                           
// %d - domain (http hostname $_SERVER['HTTP_HOST'] without the first part)       
// %z - IMAP domain (IMAP hostname without the first part)                         
// For example %n = mail.domain.tld, %t = domain.tld                               
$rcmail_config['smtp_server'] = '';

So, you have to prepend "tls://" in smtp server address. For example: tls://127.0.0.1

Also, if you disable port 25, how can other mail server communicate with your server?
