Yahoo contact help needed

[apbloom]

A potential customer with a strong Ozzie accent called from the Philipines,
and ignoring my instructions to speak clearly and distinctly, and to repeat
his number, left a garbled message on my machine. His phone number was stated, but no country code was indicated. I was able to copy part of
his email address, ending with yahoo.au.

Is there a way to contact yahoo, and find out the entire email address,
using a lookup or something similar? The part of his address that I was able to copy was rather unique, so I believe a quick search would narrow it down.

Thanks in advance for any help you can offer.

I assume you have tried googling what you have + the yahoo.au suffix?

I have had luck doing that.
