We have some difficulty on Amazon SES and potentioanlly other webservices. We never used it and could not set up and have it work for us.
We use PLESK and we need DKMI as well. And we cant sent emails with SMTP from nodejs with information given at amazon SES.
And we have some more potentail questions. We need asistance and we need SKYPE support. And a job uncompleted for us, is worthless please keep this in mind. If you know amazon web services it will not take you more than 1 hour asistance.
