Header fields - Amazon Simple Email Service

Header fields

Amazon SES can accept all email headers that follow the format described in RFC 822.

The following fields can't appear more than once in the header section of a message:

  • Accept-Language

  • acceptLanguage

    Note

    This field is non-standard. If possible, you should use the Accept-Language header instead.

  • Auto-Submitted

  • Bounces-to

  • Comments

  • Content-Location

  • Content-MD5

  • Content-Transfer-Encoding
