Email settings [email protected]
Not installed SSL

your fast response is highly appreciated

I had the same problem few weeks ago. I have dropped all configured accounts settings in nopcommerece admin panel and created newer one from scratch and luckily it started working for me.

Same solution :)
nopCommerce version 3.8

Any solution ? still having problem

Hello,

This problem is not related to nopCommerce email configuration so far as I could see. If you are able to send email within domain but not to other domains then this is a problem with your email server.

You can try to configure your email address in gmail or some other email providers and send an email from there to see if it fails. This way you will believe what i just pointed here.

Try to solve this at your end with your hosting provider.
