What is SMTP?

SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. DNS Made Easy's SMTP service provides a secure relay for sending outgoing email using SMTP Authentication.

DNS Made Easy enterprise email servers will act as a secure relay for your email messages using SMTP authentication. Many ISP's today block outgoing port 25 as a spam mitigation precaution. This is preventing many legitimate clients from sending email from their own domain names. SMTP service from DNS Made Easy will allow you to specify an alternate port for your going email relay through our server.

How the SMTP Service Works

DNS Made Easy's SMTP Service allows you to configure an account username and password so you can authenticate to our SMTP servers, after authentication you can send up to your allotted quota in email as a user from your own domain(s) and from any email account you wish. Your email client or server will need to be configured to use our outgoing SMTP server with the authentication credentials you have created.

You can configure your email client or server to send all authenticated SMTP traffic to any of the following ports:

  • SSL or non-SSL: 21, 25, 5521, 5525, 7721, 7725, 2525
  • SSL only: 465, 5555

NOTE: DNS Made Easy DNS service for your domain is required to use our SMTP services. We require all users to first create an account, configure DNS service, then call our offices to subscribe to the SMTP service for verification.
