'smtp://' prefix is required for the SMTP server name with System Recovery 18

Problem

'smtp://' prefix is required for the SMTP server name with System Recovery 18

Error Message

Error ECE3006A: Unable to send notificaiton e-mail.

ECE30072: Check the fully-qualified Domain name and port number of the SMTP server

Cause

Since Veritas System Recovery 18 supports multiple mail sending protocol, SMTP with TLS or SMTPS, it is required to specify the server type.

Solution

This issue has been resolved by Veritas System Recovery 18 Service Pack 3. 

Service Pack 3 (18.0.3) for Veritas System Recovery (VSR) 18

With VSR 18 SP3,  emails can be sent both with or without the prefix.

Note: The specified SMTP server name must match the SMTP server name which is described in the SMTP server certificate when using encryption. Thus, IP address cannot be used as the mail server name.

Workaround

Specify the mail server name with the following prefix.

1. smtp://mail-server.domain-name
   Start with 'smtp://' for general SMTP servers. TLS encryption (aka STARTTLS) can be used with the smtp server.
2. smtps://mail-server.domain-name
   Start with 'smtps://' if the mail server uses SMTPS protocol.
   Refer to the Wikipedia for more information about SMTPS protocol https://en.wikipedia.org/wiki/SMTPS
