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

[anuj-scanova]

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

[medmunds]

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.

@anuj-scanova, I moved this to Q&A. The weekly Amazon SES integration tests are working, so it seems likely this is something specific to your configuration or code. Please let us know if my earlier suggestions resolved your problem, or provide more info if they didn't.

@medmunds We had to remove the anymail dependency and use SES SMTP credentials instead. Now it is working as expected.
