Is there any SMTP 25 port restriction reason from AWS ????
Kindly help on it and give the proper resolution
port 25 is blocked by default, you have to request access. then when it is opened, you can send to external providers
@mallick you need to use port 465 to send mail since SSL is required. You will not get access to port 25.

@ssadvisor can you please provide the steps as how can we configure and use port 465, as per screenshot shared at the bottom it was written that SSL/TLS is activated.
@mallick your outbound mail seems to be using port 25 according to the picture. You have SSL on the incoming side for the server. You haven't given any picture for your SMTP setup.
