More Powerful IP Based Authentication and Account Mapping

Now, any account can be selected and authenticated by the source IP address. Simply edit the IP whitelist and add the account id to the end of the IP address separated by a pipe.

For example if you wanted all email coming from 66.72.15.29 to go through account 1024, you would enter the following entry in the whitelist:

66.72.15.29|1024

Critical Alerts

System alerts are now broken out into two levels: critical and standard. Critical and standard alerts can be sent to different email address lists, making it easy to escalate critical issues.

The alert level of each Dynamic Block Rule can now be set to standard or critical.
