It can be quite inexpensive, you’ll have full control over your […]
Apparently the full permission scope is required to do XOAUTH2 authentication in the SMTP protocol for GMail. See these examples https://www.example-code.com/vbnet/gmail_smtp_oauth2_access_token.asp https://www.example-code.com/vbnet/gmail_smtp_send_using_oauth2_token.asp The full permission scope is “https://mail.google.com/” The send-only scope is: “https://www.googleapis.com/auth/gmail.send” Google claims that it’s possible to send email with the send-only scope, but we’ve found it is simply possible. It just doesn’t work. Don’t know why. Perhaps […]
There is a big unsolved mystery: Is it possible to create pre-signed URLs for AWS services other than S3? For example, is it possible to create a pre-signed URL that allows the user to send an SES email? We simply don’t know. Theoretically it seems it should be possible. However, all AWS pre-signed URL documentation or examples has to do […]
