Bypass IE History Domains:
Advantages: Reduces the amount of false positives from SpamBully.
How it works: Will automatically allow emails from domains that appear in your Internet Explorer History list into your Inbox. However, if at least one email address from one of these domains has been added to your Block list, the domain will not be allowed to bypass the filter. This helps to prevent common domains which are used by spammers, to not bypass the filter once an email address has been added to the Block list.
Limitations: Can increase the amount of spam messages slightly when first starting to use this filter option.
Recommendations: Enable this option if you are seeing too many false positives. It will cause an initial increase in spam initially until users from common domains are added to your Block list. After that, these common domains will no longer be able to use this filter bypass feature.
