Overview

In Serv-U, you can configure an SMTP connection to send email for events which are configured to use email actions.

You can configure SMTP on the server or domain level, or both. SMTP configuration at the domain level can be inherited from the server level. The SMTP configuration dialog is located in the Events tab in the Domain Details and Server Details pages.

Environment

Serv-U version 12.x ++

  • Windows Vista/7/8, Server 2008/2012 - C:\ProgramData\RhinoSoft\Serv-U (Folder is Hidden in Windows by default)
  • Windows 2000/XP, Server 2000/2003 - C:\Program Files\RhinoSoft\Serv-U
  • Linux - /usr/local/Serv-U

Steps

Click Configure SMTP to launch the dialog, and then specify the following details:

  • SMTP Server: The name or IP address of the SMTP server.
  • SMTP Server Port: The port the SMTP server is using.
  • From Email Address: The email address to use for the outgoing email.
  • From Name (optional): The name to use for the outgoing email.
  • This server requires a secure connection (SSL): On some SMTP servers all incoming connections must be encrypted to protect against possible attacks. If your server requires that all incoming connections must be encrypted, enable this option. The default port for encrypted SMTP connections is 465. Serv-U supports Implicit SSL only, and does not support Explicit SSL (port 587).
  • My server requires authentication: To enable authentication, select this option.

If your SMTP server requires authentication, enter the following information:

  • Account Name: The account name associated with authentication for the SMTP server.
  • Password: The password for the account.

 

Testing the SMTP configuration

Perform the following steps to test the SMTP configuration in Serv-U:

  1. After specifying the details of the SMTP server and the corresponding account, click Send Test Email to test your SMTP connection.
  2. In the Send Test Email window, specify the email address where you want to send the test email to, and then click Send. Optionally, you can edit the subject and content of the test message.
  3. If the email was sent successfully, click OK on the confirmation window to save your SMTP configuration, or click No to return to the SMTP Configuration window.

If an error occurs at any stage of the configuration test, Serv-U returns one of the following error messages in the SMTP error window.

Error message Explanation
SMTP connection failed. Please check your SMTP server and port settings. The most common reason for the SMTP connection to fail is an invalid SMTP server address or port number. Verify that these details are correct.
Unable to send message due to authorization error. Please check user name and password. The connection to the server is successful, but the provided user name, password, or both is incorrect.
The error can also occur if incorrect server and port settings are specified, but the specified server is listening on the specified port.
Unable to send message due to recipient error. Please check that recipient email address is valid. The connection to the server is successful, but the email address provided in the To Email Address field of the Send Test Email window is not valid.
Unable to send a message. Please try again later. The connection to the server is successful, but an unspecified error occurred while sending the test email.
SMTP communication failed. Ensure that SMTP server settings are correct, and that the SMTP server is up and running. An unspecified error occurred. Check your SMTP connection details, and try the test again.
Timeout while contacting SMTP server. Please check that the SMTP server address is correct. The connection to the SMTP server timed out.

Troubleshooting Tips:

  1. Telnet {ip add of email server} 25, from windows command prompt.
  2. Send-MailMessage -Body 'TEST' -SMTPserver {ip add of email server}, from windows power shell Outputs of telnet.
