Daily email Autosupport

Hello everybody.

From some days, my daily email to the recipient autosupport@autosupport.datadomain.com doesn't work.I receive this error:

"Host or domain name not found. Name

      service error for name=asupeng01.isus.emc.com type=A: Host not found"

Maybe the standard email of the support was changed? How can I modify the Autosupport recipient?

Thanks in advance.
