    Please note that SES doesn't sign emails for you, you need to either use sendrawemail or SMTP to use your own signature on the client side before you even relay the emails to SES. – James Dean Sep 12 '19 at 13:53

From the documentation:

End-to-End Encryption You can use Amazon SES to send messages that are encrypted using S/MIME or PGP. Messages that use these protocols are encrypted by the sender. Their contents can only be viewed by recipients who possess the public keys that are required to decrypt the messages.

Amazon SES supports the following MIME types, which you can use to send S/MIME encrypted email:

  • application/pkcs7-mime

  • application/pkcs7-signature

  • application/x-pkcs7-mime

  • application/x-pkcs7-signature

Amazon SES also supports the following MIME types, which you can use to send PGP-encrypted email:

  • application/pgp-encrypted

  • application/pgp-keys

  • application/pgp-signature
