[Evolution] Recognizing "Junk" Header from ISP

[Jonathan Ryshpan <jonrysh pacbell net>]

Yahoo, my ISP, marks messages that it thinks are junk with a special header "X-YahooFilteredBulk" followed by what appears to be an IP address, probably that of the sender.   A few such headers are:
>     X-YahooFilteredBulk: 72.19.253.174
>     X-YahooFilteredBulk: 199.92.213.102
>     X-YahooFilteredBulk: 199.92.213.102
>     X-YahooFilteredBulk: 66.231.82.107
>     X-YahooFilteredBulk: 63.87.220.151
>     X-YahooFilteredBulk: 199.92.213.72
>     X-YahooFilteredBulk: 70.42.57.33
>     X-YahooFilteredBulk: 202.83.245.89
>     X-YahooFilteredBulk: 220.72.137.177
>     X-YahooFilteredBulk: 199.92.213.69
>     X-YahooFilteredBulk: 63.87.220.151
>     X-YahooFilteredBulk: 70.42.57.33
I would like evolution to recognize such messages as junk.  Unfortunately the setup box in
>     Edit->Preferences->Junk->Check custom headers for junk
requires the "Contains Value" field to be filled in.  What value can I use in this field?


In a related question, when I try to select messages from Inbox which have a header line starting "X-YahooFilteredBulk:" by clicking
>     Search->Advanced Search->Add Condition
to get a choice box in which I enter:
>     Specific Header  :  X-YahooFilteredBulk  :  Exists  :  <Empty Field>
nothing is selected, despite the fact that many such messages are in Inbox
Any Ideas?
