I've just had some bounces from addresses @fsfe.org with errors like "550 5.1.1 something@fsfe.org: Recipient address rejected: User unknown in local recipient table"
Do people lose their addresses @fsfe.org if they don't pay again?
If those users are non-renewers, can you please add a more meaningful error than "User unknown in local recipient table" (maybe either "gone away - please contact something@some.other.domain" or at least "user no longer known") so that poor postmasters like me can figure out the cause?
Thanks,
