I am assuming that you are setting this up with WCCP either ver 1 or 2 and requesting info specifically regarding the caching functionality of the CE (not the CDN aspect of the CE). If the above assumptions are correct, then a few things to keep in mind are:
1) WCCP by default will only redirect port 80 traffic so mail shouldn't be a concern unless you specify SMTP port 25 to be redirected.
2) The reason the CE proxies the connection is to insure that the return path flows through the CE so the content can be cached and thus get your savings. For the vast majority of applications this should be ok for those that must see the true client source IP we can use the bypass command listed here: http://www.cisco.com/univercd/cc/td/doc/product/webscale/uce/acns41/cref41/13952cli.htm#xtocid10 to have the client be passed directly through the CE (note caching will not be performed on this "bypassed" traffic.
