In some cases we wish to associate a public website with a mailing list domain.
For example Facebook send emails from the domain facebookmail.com, but we wish the score for this domain to be returned when we perform a search for facebook.com.
For our purposes facebookmail.com and facebook.com are aliased.
If you think we should add an alias then either open an issue and request it, or...
Modify the file /alias-list.dat, adding your alias in the form;
<public domain>: <mailing list domain>
For the facebook example above:
facebook.com: facebookmail.com
If a domain sends from from multiple mailing list domains, then simply include it in the list twice.
An hypothetical example being;
facebook.com: facebookmail.com
facebook.com: facebooknotifications.com
