[Dx-qsl] EX8MLE route?

[Al, N6TA via DX-QSL]

 Anybody had luck with any route to Sergey?  I have sent two direct requests to the Bishkek address.  First not received.  Sergey told me by email to try again. Another sent 4 months ago and not reply.    Now, his email address as in QRZ.com bounces as undeliverable.He has a different physical address for EX9T.  Anyone used it successfully?
Tnx for ideas.73,Al-N6TA
