E-mail notification configuration

You can e-mail Double-Take Availability event messages to specific addresses. The subject of the e-mail will contain an optional prefix, the server name where the message was logged, the message ID, and the severity level (information, warning, or error). The text of the message will be displayed in the body of the e-mail message.

• Enable e-mail notification—This option enables the e-mail notification feature. Any specified notification settings will be retained if this option is disabled.
• E-mail server—Specify the name of your SMTP mail server.
• Log on to e-mail server—If your SMTP server requires authentication, enable this option and specify the User name and Password to be used for authentication. Your SMTP server must support the LOGIN authentication method to use this feature. If your server supports a different authentication method or does not support authentication, you may need to add the Double-Take Availability server as an authorized host for relaying e-mail messages. This option is not necessary if you are sending exclusively to e-mail addresses that the SMTP server is responsible for.
• From address—Specify the e-mail address that you want to appear in the From field of each Double-Take Availability e-mail message. The address is limited to 256 characters.
• Send to—Specify the e-mail addresses that each Double-Take Availability e-mail message should be sent to. Enter the addresses as a comma or semicolon separated list. Each address is limited to 256 characters. You can add up to 256 e-mail addresses.

• Subject prefix and Add event description to subject—The subject of each e-mail notification will be in the format Subject Prefix : Server Name : Message Severity : Message ID : Message Description. The first and last components (Subject Prefix and Message Description) are optional. The subject line is limited to 255 characters.

  If desired, enter unique text for the Subject prefix which will be inserted at the front of the subject line for each Double-Take Availability e-mail message. This will help distinguish Double-Take Availability messages from other messages. This field is optional.

  If desired, enable Add event description to subject to have the description of the message appended to the end of the subject line. This field is optional.

• Includes these events—Specify which messages that you want to be sent via e-mail. Specify Information, Warning, and/or Error. You can also specify which messages to exclude based on the message ID. Enter the message IDs as a comma or semicolon separated list. You can indicate ranges within the list.

  You can test e-mail notification by clicking Test. By default, the test will be run from the machine where the console is running. If desired, you can send the test message to a different e-mail address by selecting Send To and entering a comma or semicolon separated list of addresses. Modify the Message Text up to 1024 characters, if necessary. Click Send to test the e-mail notification. The results will be displayed in a message box.

  E-mail notification will not function properly if the Event logs are full.

  If an error occurs while sending an e-mail, a message will be generated. This message will not trigger another e-mail. Subsequent e-mail errors will not generate additional messages. When an e-mail is sent successfully, a message will then be generated. If another e-mail fails, one message will again be generated. This is a cyclical process where one message will be generated for each group of failed e-mail messages, one for each group of successful e-mail messages, one for the next group of failed messages, and so on.

  If you start and then immediately stop the Double-Take service, you may not get e-mail notifications for the log entries that occur during startup.

  By default, most anti-virus software blocks unknown processes from sending traffic on port 25. You need to modify the blocking rule so that Double-Take Availability e-mail messages are not blocked.
