How do I set up AWS SES?

Question

Amazon Web Services

There is a php application, everything seems to be set up according to this article
. Everything worked, but letters stopped coming to some addresses.
What could be the problem? Does Amazon block too frequent emails to the same address?
Sending is carried out in the same way. I don't see any issues with console.
php -r 'mail();';
Not in spam either.

Answer 1

The problem was solved when I replaced the original script with PHPMailer
