@EI_Rulo,

If you’re encountering an issue with the “Send SMTP Mail Message” activity in UiPath and the error message mentions “relayloopback,” it typically indicates that the SMTP server is configured to reject emails that are sent to the local domain or loop back to the server itself. This is often a security measure implemented by SMTP servers to prevent email loops or abuse.

Here are a few steps you can take to resolve this issue:

  1. Check SMTP Server Settings: Ensure that you have configured the correct SMTP server settings in the activity properties. Double-check the hostname, port number, and any authentication credentials required.
  2. Use a Valid Recipient Address: Make sure that the email address you are trying to send to is valid and not pointing to the local domain of the SMTP server.
  3. Check SMTP Server Configuration: If you have access to the SMTP server configuration, verify that it allows sending emails to external domains and does not block emails with loopback addresses.
  4. Test with Different SMTP Server: If possible, try using a different SMTP server for sending emails. You can use public SMTP servers like Gmail SMTP for testing purposes.
  5. Contact System Administrator: If you’re working within an organization, contact your system administrator or IT support team for assistance. They might be able to provide insights into the SMTP server configuration or any restrictions in place.
