I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check the McAfee console and see if there is anything going on. Maybe getting hit with DoS or something.
By the sound of it, looks like McAfee has a either connection or email rate per whatever configured on the device. Validate on which connector that's happening - Inbound to McAfee from the Internet or McAfee to the Exchange server/s.

like is there any standard email rate should be there? I am trying to google but cant find out
pramod1Author Commented:
it is from mcafee to exchange
It should be in McAfee manual for the corresponding appliance version.
For Exchange - here.
pramod1Author Commented:
so I should check on exchange?
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
I would start at wherever that message is originating (Exchange or McAfee?).
so I should check on exchange?
It looks like McAfee-related incoming rule, however you need to validate this based on the area that this particular log corresponds to.
In general, in your particular setup, I would advise against any Exchange-related changes, at this point in time.
