ZD2 - POP Account Not Respecting Account Settings

[Danno321]

I set up a POP account (Delete messages on the server after downloading them) in Webmail and set "Messages sent from this account have the following settings:" to the POP account email address. When I reply to a POP account email in Webmail, Zimbra sets FROM to the POP account email address. But in ZD2 on Mac, Zimbra instead sets FROM to my native Zimbra account email address. Using a Persona does not fix this problem either. Is this a ZD bug?
