This is also easy with a proxy filter, by passing the message on, but
replying with 5XX to "." even when the downstream replied with "2XX".
Of course you still need an elementary proxy filter that just stutters
all commands and data downstream, but edits the "." reply. Not too
hard to write, but I don't have any handy pointers to an off-the-shelf
implementation.
