not able to use SMTP for sendmails

[srikanth.kallu]

I am getting an error when trying to use SMTP

Not sure about the mistake i am doing

Can you please correct me

It seems that the first and second images are different. The first is sending without encryption. Whereas the second is using TLS. On port 25 there generally is not encryption, and instead that would be likely handled with port 587. Could you verify which way was intended and maybe try both on your network?

Actullly i tried in all the ways, but it did not work.

Have you checked the mail logs on the relay to verify if the relay is receiving the emails?

I found it, it is my nagios password not updated.

Thanks and i appreciate all for looking into this.
