"Command RCPT failed"

Overview

The error indicates that the SMTP server has not accepted the recipient's email address.

Cause

The Command RCPT failed error indicates that the SMTP server has not accepted the email recipient's address. Some possible causes are that:

• The email address is not in valid format.
• The SMTP server is limiting the scope of allowed recipients.
• Provided FROM address is not allowed.
• Most likely, the user authentication is required.

Solution

If the error returns a message similar to those above, it means that authentication with the SMTP server is required and thus has to be configured properly. Go to the Email tab of Automation Workshop Options (accessible from the Tools menu) and make sure that a Username, Password and Authentication method are correctly specified.

If unsure about SMTP server parameters or would like to use Gmail as SMTP, read more on SMTP server configuration.

Summary

Common causes of the SMTP error:

• FROM address not allowed (you must use the same address as for authentication).
• TO address not permitted.
• Authentication required to send outside your organization.
• SSL or TLS encrypted connection required to send emails.
