Submission Acknowledgement not deliverying to authors

Dear Sir,
I have configured SMTP details in the file.

But, the system not sending an acknowledgment to the authors.

Submission Acknowledgement

  • Application Version - OJS

I have read previous posts but there is no proper explanation. Can you please help me in this regard?

Please note: There is no error notification during submission.

Hello @aurag,

Just to confirm, are other types of emails being sent correctly? Additionally, were you or your host able to check the mail server’s error log?

Yes, Sir. Example- reviewer assignment. Notification of new reviewer inclusion. Changing role of the users.

Only, submission acknodgment not deliverying to authors.
