Synametrics SMTP Gateway


Synametrics Smtp Gateway has reached end-of-life and is no longer being developed. Consider using Xeams instead, which provides contains every feature provided by SMTP Gateway.
Synametrics SMTP Gateway is an SMTP server that can be used for two purposes:
  • As a backup e-mail server - This is done by adding an additional MX record in the DNS server with a lower priority. The sender's e-mail server will try to send messages to your primary server. If that is not available, it will attempt to send it to the SMTP Gateway, which is acting as a backup server. When your primary server comes back up, messages will be delivered to its final destination.
  • Load balancing for outbound messages - Users can use the Synametrics SMTP Gateway to send outbound messages to recipients on the Internet. This elevates a significant load from your primary e-mail server, particularly if you need to send outbound messages to hundreds or thousands of recipients.
