$append_addr
$append_addr : boolean
By default, if more than 1 address header is found, the addresses are appended together into a single field. Set this value to false to ignore all but the *last* header.
This class represents address fields (RFC 5322).
sendEncode(array  $opts = array()) : array
                Returns the encoded string value(s) needed when sending the header text to a RFC compliant mail submission server.

getAddressList(boolean  $first = false) : mixed

A Horde_Mail_Rfc822_List object (if $first is true) or an array of those objects.
