We've just been observing a user through pages on our site under the "Current Page" feature on the HCL popup.  We just noticed the current page changed to a page not on our server! The page was:

hxxp: mail. iinet. net. au/mail/sendmail. pl

User Agent
Microsoft Internet Explorer - Mozilla/4. 0 (compatible; MSIE 8. 0; Windows NT 6. 1; WOW64; Trident/4. 0; GTB6. 4; SLCC2; . NET CLR 2. 0. 50727; . NET CLR 3. 5. 30729; . NET CLR 3. 0. 30729; Media Center PC 6. 0)

What's happening and should we be concerned?
