Hi There,

You are talking about O365 but your post title is Exchange 2010?

As you are talking about Hub and CAS server, I assume that's a 2010 on premise??

I am talking about exchange server 2010 , I referred to DNS connector delivery because the count is high and we have office 365 as well

are you on hybrid deployment. AD Sync?
Have you looked at the queues and confirmed what the next hop is? As its DNS queues I imagine this is outbound from your organisation.

Do you use any smart hosts? (Messagelabs, ironport etc...)

I see inbound emails from proofpoint, but the spike is going low and high is it because of office peak time
That is very possible. As long as they are dropping again there should not be any issue. If the queues are rising and remaining up there, there will be an issue somewhere.

Otherwise, this may just be peak traffic.

How many mailboxes are we talking about?
