Cant receive email from Instegram

[Sahar541998]

I created a basic SMF with basic configuration

I configured only that SMF_CONFIG to forward all the emails from my domain to my Gmail account

I Tested the SMF by sending email to my domain and it did work !!

But when I try to register to Instegram for example with the domain name the SMF wont forward my mail...

I tried to use docker logs to try to resolve the error but I don't receive any error or any log about the email!
(when I send from my other Gmail account to the domain I do see the logs)
I have Azure domain so I don't have client for the mail

So please help me what could be the problem
Do I need SSL or Something like this?
why I don't see any logs that indicated that email received

Some logs:
