# KI.GWB.6024 – Email report fails using SMTP 'None' auth type

Email reports failed with the SMTP 'None' auth type. Fixed.

Applies to: `Guardian Classic`

| Created | Found in Release | Fixed in Release | Last Updated | Reference ID | **Status** |
| --- | --- | --- | --- | --- | --- |
| 20th September 2024 | V3.46.0 | V3.48.1 | 24th September 2024 | KI.GWB.6024 | `Working as Expected` |

**Problem**
:   For email reports sent via SMTP, if the authentication type was set to 'None', the action was failing and the following error message was displayed, 'check\_auth\_args: wrong authentication type none'.

**Cause**
:   This issue was caused by an underlying change in Rails that impacted the mailer functionality.

**Solution**
:   This issue was resolved in V3.48.1 of Guardian. Now, email reports sent via SMTP work without error messages when the authentication type is set to 'None'. Upgrade to V3.48.1 of Guardian (or later) to resolve this issue.

**Workaround**
:   There is currently no workaround available for this issue.
