    That's just it, while a human *can* decode it a harvester cannot.  It is a
valid address.  Furthermore if you think a human is going to scan the address
list to pick out/decode the addresses then, uh, whatever.  But supposing a
human did it would be passed over since it is a valid address, looks like a
valid address at a passing glance and without context would NOT be caught as a
munged address.

    No, it isn't an extra mailbox and no, I don't check it.  It is a different
subdomain which exim is configured to reject outright.  Like I said,
essentially the same address, it is valid, all the work is done on my machine,
doesn't look like it is munged to a cursory human glance.
