Yahoo mail / DNS admin on the list?

[bryan at shout.net (Bryan Holloway)]

Having an intermittent issue where Yahoo's mail-servers keep complaining 
about not finding MX records for a small handful of customers (and 
always the same customers.)

Tried submitting a ticket through the postmaster web-site but haven't 
gotten any response.

Could someone contact me off-list? It would be greatly appreciated.

Thanks!
