I did not receive the administrator's email (SES )

[shiihara]

Hello, everyone.
I'm a fledgling developer.

I am currently setting up my email in SES, I tried to set up a different email address for the administrator of user@example.com but I don't get the email.

I've confirmed that I can receive mail with Thunderbird mailer. I don't know why it doesn't reach me when I use canvas-LMS.
I'm wondering if you have any tips?

Settings below.

---

production:
  delivery_method: :smtp
  enable_starttls_auto: true
  address: e-mail-smtp.ap-northeast-1.amazonaws.com
  port: 587
  user_name: AKIAWxxxxxxxxxxxx
  password: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  authentication: plain # plain, login, or cram_md5
  domain: "aaa.net"
  outgoing_address: admin@bbb.com
  default_name: Instructure Canvas

---

aaa.net domain is SES-verified
admin@bbb.com is also verified
I also know that SES only works with TLS.

I'm not very good at English, so I use translation software. I'm sorry if it's hard to understand.

Anyway, I found out that I needed another MTA, so I installed postfix.

I used sendmail command to check the arrival of the mail, but I didn't receive any mail from canvas-LMS.

Please give me a hint.

I forgot to mention that canvas-LMS was installed from the AWS marketplace.

I downloaded the 2020/8/12 version back from the AWS marketplace and it worked. The bug?
