Advanced Configuration

SMTP Server

  • Protocol: the protocol connection, select SMTP ot SMTPS. To add a trusted certificate to Genius Server, refer to the Certificate Provider (Conf) section.

  • SMTP hostname: the hostname of the SMTP server.

  • SMTP port: the port used to listen (mostly 25).

  • SMTP username: the user of the SMTP server.

  • SMTP Password: credentials used for the authentication. If the authentication in not required for the server, do no fill fields in. To change the password, press Change Password and enter it twice.

  • StartTLS: it is a way to supplement an insecure communication protocol with a secure connection using SSL/TLS. StartTLS is defined for SMTP, IMAP, POP3, LDAP, FTP and other protocols and even though TLS or SSL connection are used, it avoids using a separate port for the encrypted communication.

    • DISABLED: by default the communication between the Genius Server and SMTP server is performed in plain text.

    • ENABLED: the Genius Server attempts to use StartTLS with SSL/TLS. If the remote peer does not support StartTLS, or peers cannot agree on a cryptographic protocol and cipher, the Genius Server falls back on an unsecured communication protocol.

    • ENABLED ADN REQUIRED: the Genius Server attempts to use StartTLS with SSL/TLS. If the remote peer does not support StartTLS, or SSL/TLS handshake fails, the connection terminates. No fallback to a connection without security is made.

Note

StartTLS is only used with SMTP protocol.

  • Timeout: the timeout connection to the SMTP server before it is considered unreachable.

  • MIME address strict: enables the strict parsing of addresses, according with RCF822. If disabled, illegal addresses, that sometimes occur in real messages are allowed. The default is true.

  • Attachment as URL enabled: if checked, it enables the replacement of all attachments by a link for the download.

  • Max attachment threshold size: the maximum size for attachments to be sent through an email.

Users can verify the right configuration for the selected protocol. To send an email, click on the Send test email menu button, enter the sender (Email from) and the recipient (Email to), and press the Test button.

To verify that the email has been sent, check the mailbox the email has been sent to.

If the configuration is wrong, the result should be an error. If the configuration is right, the mail is sent to a recipient.

To delete an existing mail server, press the Delete button next to it. To modify an existing mail server, press the Edit button next to it.

For further details about characters encoding in attachment filename, refer to the Email section.

To save, press the Save button and then Back.

Note

After configuration changes have been made, restart the Genius Server.
