MailFrontier Desktop maintains Allowed/Blocked lists for People, Companies, or Mailing Lists.

How Allowed and Blocked lists work
The “Allowed” list should contain only those people, companies, and mailing list entries that you always want to receive email from. When an email is received where the “From:” field matches an entry on one of the Allowed lists it gets a “Free Pass” and that email goes to your inbox.

The “Blocked” list does just the opposite. When an email is received where the “From:” field matches an entry on one of the Blocked lists it goes to the MailFrontier Junk Mail folder.

People Allowed and Blocked lists
MailFrontier Desktop will automatically build and update the People Allowed and Blocked lists. You can also edit these lists. When you send an email to someone their email address is added to your People Allowed list. The same thing happens when you “Unjunk” an email. If you “Junk” an email the email address of the sender is placed in your People Blocked list.

Company Allowed and Blocked lists
These lists are only updated by you by adding the domain name (mailfrontier.com for example) to the appropriate list. An email which arrives where the “From:” domain name is listed on the Companies Allowed list will get a free pass and goes to your inbox. An email which arrives where the “From:” domain is listed on the Companies Blocked list goes to the MailFrontier Junk Mail folder. It is important to understand that when using Company Allowed/Blocked lists that all email addresses from the domain listed will be allowed or blocked accordingly.

Mailing List Allowed list
This list is only updated by you. Any email addresses added to this list will mean that email which has the “From:” or the “To:” field on this list will get a free pass and be delivered to your inbox.
