Hey there, HowToForge Forum! I've looked for a solution for this all around the internet, and usually, I don't post but I couldn't really find any useful post or tutorial. Therefore I really hope that one of you clever minds can help me out on this problem. I've just installed ISPConfig on a fresh machine and followed "The perfect server" on ubuntu 20.04, but when I try sending a mail I get SMTP error 250. config.inc.php Code: <?php $config = array(); // Do not set db_dsnw here, use dpkg-reconfigure roundcube-core to configure database! include_once("/etc/roundcube/debian-db-roundcube.php"); // The IMAP host chosen to perform the log-in. // Leave blank to show a textbox at login, give a list of hosts // to display a pulldown menu or set one host as string. // Enter hostname with prefix ssl:// to use Implicit TLS, or use // prefix tls:// to use STARTTLS. // Supported replacement variables: // %n - hostname ($_SERVER['SERVER_NAME']) // %t - hostname without the first part // %d - domain (http hostname $_SERVER['HTTP_HOST'] without the first part) // %s - domain name after the '@' from e-mail address provided at login screen // For example %n = mail.domain.tld, %t = domain.tld $config['default_host'] = 'localhost'; // SMTP server host (for sending mails). // Enter hostname with prefix ssl:// to use Implicit TLS, or use // prefix tls:// to use STARTTLS. // Supported replacement variables: // %h - user's IMAP hostname // %n - hostname ($_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 $config['smtp_server'] = 'localhost'; // SMTP port.

Peter.
You must include tls: in the smtp_server if using port 587. The next issue you hit may be the server name is not in the certificate, for which you can use a different server name, configure roundcube to not verify the server name, or change to port 25.
If the smtp_server is on localhost, it's fine to use port 25, so change $config['smtp_port'] = 587; to $config['smtp_port'] = 25;
Hey there, Thank you guys so much for your help. Now I can send emails successfully, but I don't receive them. I have changed smtp_port to 25.
