GP Mail: Unexpected internal exception during background execution

Hi,

I have designed a process in Guided Procedures which send mails when Approved or Rejected. I get an exception for users who have yahoo or gmail IDs.

Technical Exception:

Unexpected internal exception during background execution: The message contains non-trusted or invalid receivers

Is there any setting /configuration for sending mails to these.

Pl help

Thanks,

Vasu
