 Listfix does some rewriting of the headers before it replicates an email to the
 recipients. Since it is creating a new email, most of the original email
 headers are no longer useful and are stripped away. Some of the original headers
 are kept, such as 'To', 'Cc', 'Subject', and certain content related headers
 that are required to maintain the integrity of a multipart email body. The
-'From' header is readdresses so that the it contains the same user@domain as the
+'From' header is readdressed so that it contains the same user@domain as the
 email list itself. This is necessary to avoid emails being flagged as spam, 
 because it is almost a certainty that your email server is not listed as an
 official sender for the domain name of the original 'From' address.
