No mail from Yahoo to Iburst

[Daveb]

Over the past few days I have received no email from Yahoo (normally 10-20 per day), so I sent a test mail and this is the failure message received at Yahoo.

Can someone from Iburst please investigate as I have previously queried disappearing email only to be told you have no record of any rejection of mail, but it seems that your mail servers are not always contactable from overseas causing non-delivery.
I have not contacted your call centre as in the past I have found that their only reply is "We have no problems".

Thanks.
