In the Section 7.2.14. Discussion History of the XEP-0045 (Multi-User Chat) it is presented the Extended Stanza Addressing (XEP-0033) Type “ofrom”:
If the room is non-anonymous, the service MAY include an Extended Stanza Addressing (XEP-0033) [16] element that notes the original full JID of the sender by means of the “ofrom” address type:
Example 36. Discussion History Message with Original From
<message
from='coven@chat.shakespeare.lit/firstwitch'
id='162BEBB1-F6DB-4D9A-9BD8-CFDCC801A0B2'
to='hecate@shakespeare.lit/broom'
type='groupchat'>
<body>Thrice the brinded cat hath mew'd.</body>
<delay xmlns='urn:xmpp:delay'
from='coven@chat.shakespeare.lit'
stamp='2002-10-13T23:58:37Z'/>
<addresses xmlns='[http://jabber.org/protocol/address](http://jabber.org/protocol/address)'>
<address type='ofrom' jid='crone1@shakespeare.lit/desktop'/>
</addresses>
</message>
So, the org.jivesoftware.smackx.address.packet.MultipleAddresses.Type enum should have the “ofrom” value.
