Subject: Issue with Outgoing Emails via SMTP Outbound Relay for deercreekrentals.net

Body:

Hello Dynu Support Team,

I’m writing from Deer Creek Rentals Inc. regarding an urgent issue with the SMTP outbound relay service for deercreekrentals.net.

Here’s the situation:

When I initially created and tested the deercreek.net website—both in development and live environments—our contact and application forms worked perfectly.

However, over the weekend, a visitor informed me that the application form was no longer working. Upon testing, I found that all submission forms—contact, application, etc.—are now failing.

After submitting a form, the site responds with a Server 500 error.

I have already restarted both nginx and gunicorn, but the issue persists.

Given this, I’m wondering if there have been any recent service changes or issues on your end that might be impacting SMTP outbound relay functionality for my domain.

Below are my current SMTP configuration settings:

EMAIL_HOST = relay.dynu.com
EMAIL_PORT = 587
EMAIL_HOST_USER = relay@relay.deercreekrentals.net
EMAIL_HOST_PASSWORD = DeerCreek_1
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = Deer Creek Rentals Inc <relay@relay.deercreekrentals.net>
CONTACT_EMAIL = contactagent@deercreekrentals.net
ADMIN_EMAIL = leon@orbitalravaz.com


I’d greatly appreciate your assistance in investigating:

Whether there are any known issues or maintenance events affecting SMTP outbound relay services around this time.

Whether any recent changes have been implemented that might alter how relay authentication or connections need to be configured.

Any recommendations or diagnostics I should run to determine whether this is a connection/authentication issue on my end versus something on the Dynu side.

Thank you for your prompt attention to this matter—our website relies on form submissions to function correctly. Please let me know if you need any server logs or additional information.

Best regards,
Leon
