These are the properties of the e-mails I get back from Topica and presumably other subscribers have the same. Popastro is the domain name for the Sociey for Popular Astronomy.
I can't see how I can make it come from another e-mail address unless I use my own which would mean adding and deleting subscribers. The Topica system is fully automatic and I don't have to do anything apart from upload the bulletins.
