i just tried to send an e-mail invite to my ZT network and got the following message:
535 Signature Version 2 is deprecated for use with SES from March 26, 2021. From that date on, we are progressively rejecting such requests. To resolve the issue, you must migrate to Signature Version 4. If you created your SMTP credentials in the SES Console, please create new credentials and replace the former ones. If you are deriving Signature Version 2 credentials from a IAM user, please start using the Signature Version 4 algorithm: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html
It appears Zerotier’s Amazon SES account needs updating?
Let me know if I’m missing something.
