Email delivery failure

General

Mail delivery is successful if I do it from localhost.

Unable to send email from an application after moving to cloudflare.
Error is “A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ipaddress”

Can you give your domain name?

The problem is at your mail server or your mail client. Cloudflare settings are correct (assuming that is your mail server IP address) and the mail server there is accepting connections.
