Yes, it is possible I think there is a plugin called MailMan which was made by Inrego.
I have made my own so I know it's possible to do if you want to code it yourself, no one PM me for it... not public.
Auction House is a joke with all the undercutters and mass posters, most of the time my auctions would expire so I had to use C.o.D, tell Inrego to make an Auto Blacklist function too ^^ tell him it's in the WasReturned Property.. he'll understand.
