An error occurred (InvalidParameterValue) when calling the SendRawEmail operation: Missing final '@domain'

[Anuj Sharma]

Reporting an error? It's helpful to know:

• Anymail version: django-anymail[amazon_ses]==8.6
• ESP (Mailgun, SendGrid, etc.): AWS SES
• Your ANYMAIL settings (change secrets to "redacted")

EMAIL_BACKEND = "anymail.backends.amazon_ses.EmailBackend"
ANYMAIL = {
    'AMAZON_SES_MESSAGE_TAG_NAME': 'Type',
    'WEBHOOK_SECRET': os.environ.get('ANYMAIL_WEBHOOK_SECRET', '')
}

• Versions of Django, requests, python
  ** Django: django==3.2.14
  ** requests: requests==2.28
  ** python: 3.9
• Exact error message and/or stack trace

SES IAM permission is giving the following error

It looks like SendRawEmail is not supported.
There looks like SendEmail and SendBulkEmail are two permissions required

[Mike Edmunds]

I don't think that has anything to do with IAM permissions. That error message seems to be saying one of the email addresses in your message is missing an '@​domain'.

What are the from_email and to addresses involved? Are they valid email addresses? Any commas appearing outside quotes? (Have you set whatever django-allauth uses to specify the from address?)

As far as the IAM console warning, it looks like you're in a section for managing Pinpoint Email, which is a separate AWS multichannel marketing communications service built on top of Amazon SES v2. Anymail uses the ses:SendRawEmail API from SES v1, and has nothing to do with Amazon Pinpoint.
