How do I activate my SMTP account?

To activate your SMTP account you should click on the link in your activation email.

The activation link will look like this: https://smtp-server.com/cgi-bin/activate?id=161404&cod=AAABBBGGHDEG

The activation email should arrive immediately after the registration is completed. The purpose of an activation email is to verify that the email address you provided is valid. If your activation email has not arrived, you can resend it.
