Some mail messages not delivered to my account

Hi,

Since yesterday I can't receive mails from gmail or google app acounts and perhaps others.
When somebody sends me an email gets this message:

This is an automatically generated Delivery Status Notification

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipient has been delayed:

     "myemailaccount"

Message will be retried for 2 more day(s)

Technical details of temporary failure:
DNS Error: DNS server returned general failure














Thanks
