SMTP Authentication Bypass

SMTP Authentication is a security measure that can be very beneficial in the fight against spam and unauthorized email as it forces the sender to authenticate their username and password before an email is sent through the mail server. Unfortunately, some applications do not have support for SMTP authentication when sending mail. Most often, these are web sites that have automated mail sending mechanisms.

The solution is to add the IP addresses of these servers/sites to SmarterMail's SMTP Authentication Bypass. Any IP address entered into this page will not be asked to provide an SMTP Authentication login. In this list you can see all IP addresses that are bypassing SMTP Authentication.

To get started, click the security icon and click SMTP Authentication Bypass in the navigation pane. A list of bypasses IP addresses will load in the content pane and the following options will be available in the content pane toolbar:

  • New - Adds a new IP address or IP Address Range to bypass.
  • Edit - Edits the selected IP address.
  • Delete - Permanently removes the IP address from the SMTP authentication bypass list.
