Unbale to find IP's from 'Recieved:' headers

[GoogleCodeExporter]

What steps will reproduce the problem?
1.use IMAP Folders
2.Add header "Received" to the "Search more headers"
3.Use headerre:Received=/^.*10.*$/ as the searcher

What is the expected output? What do you see instead?

I woudl have expected the IP to be shown that had the value 10 in it

What version of the product are you using? On what operating system?

Thunderbird 24.3.0 
Linux
Addon - 0.8.8

Do you see any errors in Error Console?
No


Please provide any additional information below.

When I use:

headerre:Received=/^.*$/

This works fine, it find everything, yet when I try to find a specific IP in 
the headers I'm unable to. 

Is there a specific JS regex that needs to be used to find the IP only.   An 
example, "received line" would be:

Received: from m10-46-65-193.cus3.tele2.bk ([10.46.65.193])

(IP changed)

Thanks in advance!
