Is anyone having problems with recipients' mail servers rejecting mail from Listserv with these sorts of messages: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) 550 5.7.1 <[log in to unmask]>... Relaying denied 550 5.1.1 <[log in to unmask]> ... relaying is Not allowed here 550 <[log in to unmask]>... Relaying denied Is there a way around apart from using the short822 or full822 list options? Andrew
