Hi everyone,

I am working on refining the email functionality in the FullCalendar app to ensure that notifications are sent to users on the event date. While troubleshooting, I encountered and resolved an SMTP server error that was initially blocking the email functionality. However, even after fixing the SMTP issue, the email is still not being delivered.

Here is a detailed breakdown of the issue:

1. SMTP Error Resolution:

   • Initially, the SMTP server was throwing an error, preventing emails from being sent.
   • I fixed the error, and it now appears resolved.

2. Logs Indicate "OK" Status:

   • After resolving the SMTP issue, I tested the email functionality.
   • The action logs show a status of "OK" with no interruptions, suggesting that the email-sending process completes successfully.

3. Current Issue:

   • Despite the logs showing a successful process, no email reaches the recipient's inbox.
   • I suspect the issue might involve message filtering, queuing, or some other server-level configuration.

I have attached two screenshots for reference:

• Screenshot : Displays the current logs showing the "OK" status after the SMTP fix.

Question: What could be the possible reasons for emails not being delivered despite the logs showing a successful process? Are there specific areas I should focus on, such as spam filters, server configurations, or email headers?

Any insights or suggestions would be greatly appreciated!

Thanks in advance!
