I am trying to use Amazon Simple Email Service to send email from NT. When configuring SMTP email settings from Options > Misc I get the error "Authentication required".
Drilling into the Amazon knowledge base I found the instructions to test the SMTP credentials using Powershell and it works ( https://docs.aws.amazon.com/ses/late...mand-line.html ). With Powershell, emails are being sent.
What could be the issue?
