[Dx-qsl] 4M9YY route?

[Don Novy]

  I've seen the postings about 4M9YY lately and was wondering
if anyone had received a reply from the address posted in
425 DX News.

  Pakmail (10012)
  P. O. Box 025304
  Miami, FL  33102-5304

  This was listed as a mail drop and is still listed on
Buckmaster.  I sent a self-addressed envelope and US $2, but
haven't received a reply.

  Did anyone receive a reply from this route?  Is this address
for W4SO who isn't the manager?

Tnx,
Don
