IS Amazon Lightsail blocking all kinds of ports?

Question

So I moved my website/service to Lightsail, but I cannot send verification emails to my users using basic php mail() command.   
So after some digging Amazon claims they just flat-out block port 25, and you have to request special access for that port.  
Ok so I requested access and they immediately denied me, giving no specific reason.
So then they tell me I need to sign up for Simple Email Service to send transactional emails.  
Ok so I sign up, and but the smtp server they give doesn't respond to any kind of connection ping/telnet/ssh (email-smtp.us-east-2.amazonaws.com)
So I've also tried to have a smtp script connect to gmail, but that doesn't seem to work either.
How can I tell what ports are blocked on this server, and unblock them?
How can I simply have password reset emails, signup emails sent out from a lightsail server?  Is this even possible?

You can call Amazon SES programmatically, or by configuring sendmail. Here is the [user documentation](https://docs.aws.amazon.com/ses/latest/dg/Welcome.html).

Without knowing the specifics of your application, let me point you specifically to two sections of that documentation:
1. [Using the Amazon SES SMTP interface to send email](https://docs.aws.amazon.com/ses/latest/dg/send-email-smtp.html)
2. [Using the Amazon SES API to send email](https://docs.aws.amazon.com/ses/latest/dg/send-email-api.html)
