This is normal and by design, which has been the same since day one 3 years ago.
If an email account is checked for new messages, data is used regardless if any new messages are downloaded.
I think the question that the OP is asking is why the phone is using the 3G connection rather than established wifi.

Thanks for the quick response. What you have said makes sense but there is no rhyme or reason to he data used. I reset my cellular data counter to zero so both sent and received read zero. I was connected to wifi and let the phone to go into sleep mode. I waited about ten minutes and sent myself the same email four times, each with a 750 kb attachment. It was sent to my .me address so it was push mail on my phone. Sure enough I checked a minute later while bringing the phone out of sleep mode and checked the data. It showed just 10kb sent but 1mb received which just doesn't tally with the 4 x 750kb mails received. It just isn't making sense.

Are you sure about data being used to ping for SMS/MMS?
