Joan- I have been talking to Listmaster about it. I think this is how MailMan is supposed to work and usually it is a good thing in that you don't have to go adding all the secondary email addresses to the Accept List if the person prefers to send list mail from another address but uses their subbed address as a Reply To address. It's only an issue where spam is concerned. I think as long as admins KNOW about it, it isn't a problem. Joan In a message dated 6/27/2012 11:50:15 A.M.
