Failed to authenticate on SMTP server with username "XXXXXXXX" using 2 possible authenticators

Email verified and domain verified and i have a below policy for ses { "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Allow", "Action": [ "ses:", "ses:SendRawEmail" ], "Resource": "" } ] }

my ses is reintated few hours ago and changed the smtp credentials does it means i need to verify the email address again
