Its working now. It took 7 days for amazon aws team to respond. Most peopel will quit and go for digital ocean or someone with better customer service. 
What amazon should do is find a way to give 1000 email per month on each account. If anyone need more then it can be charged or something. 
How it should be done , i dont know.  Port blocking ? may be they can have special chat to respond faster.
Not everyone is server admin. So in order to save people time there need to be better smarter way to fix than make people wait for 8 days.

First response from aws , no we cant do .  No reasons given. Anyways now i go and test my postfix email hook to see if i can solve outgoing spam.

I am also facing similar issue. And also I am contacting and submit all details how my website use emails, like wordpress website contact form and some leads collection email from admin@domain name to any other gmail id etc. But all these explanation aws team simply deny my request with no any additional details. 
For 1 domain i need only 1 admin@ id so, I am configure zoho mx dns and using free zoho emails along with lightsail bitnami wordpress hosting.

But for my another domains have subdomains with multipal emails and this time its a lightsail ubhuntu plesk panel. This case, plesk panle roundcube emails created and forwarder used but still its not work. 
I am also waiting for email & smtp solution for same question. Aws Hosting is great but email solution extra headache. Anyone have any fine solution for this..?

You must submit a request to allow SMTP traffic. See instructions here: https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/
