[plug] mail - multiple send addresses to plug list

[Kenworthy Family]

Hi,
    I am subscribed from home but can read plug mail from work via
iinet/webmail - however I cannot send messages from webmail (must use a
different send address I guess).  Is there a way around this without
subscribing from my murdoch account and then receiving two copies of
everything?  Enable multiple send to plug addresses for a plug list
member?
