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?
