Question
How to send emails using droplets?
Hello person
Recently Digital Ocean has released my account to perform e-mail sending off the server.
The problem is that whenever I send an email to Hotmail.com or some other Microsoft address the emails return instantly.
I did the test by sending it to Gmail, and the email came directly to Spam.
How do I fix these problems?
The return email from microsoft is this:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
