Incoming mail delay of several hours

My incoming mails are being delivered several hours behind. See the headers below. When is this problem with mail3/dspam2 going to be rectified?

It appears like a massive botnet attack that seems to have caused this slowness. We are taking all measures to handle this and will post an update about it soon.
