Some emails that are being sent to a google apps email address are delayed (by almost 7 minute in the example below). They seem to be delayed at some machine with a 10. ip address. Is that 10. ip address internal to google? Or internal to my ISP?

This is the free version of google apps for business, thus comes with no support. Is there anything I can do to avoid this delay (other than using a different email provider, which I will probably try just to compare)?
Edit: Thanks for all the great comments & answers. At the risk of getting downvoted, since this crowd has at least noticed these delays with gmail, would anyone care to suggest an alternative email service without such (or at least with less) delays? I would like to be able to poll for new email every 30 seconds or so.
