SMTP Authentication Bypass

SMTP Authentication is a security measure that can strongly help in the fight against spam and unauthorized email. 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 the 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.

Add IP(s) - Click on this button to add additional IP addresses to the bypass. More information can be found below.

Delete Link - Clicking on the delete link next to an IP removes it from the bypass.

Adding a Bypass

IP Address - Enter a single IP address in dotted quad notation (X.X.X.X) in this box if you want to bypass only a single IP (ex: 192.168.1.26).

IP Range - Enter a range of IP addresses in the two boxes, and all IP addresses that are contained in the range will be bypassed (ex: 192.168.1.1 - 192.168.1.255).
