Initial Comment:
1. Privoxy 3.0.6 (Windows binary with Vidalia and Tor bundle)
2. WinXP SP2
3. IE 7.0.5730.11 on WinXP Home Edition
4. http://mail.yahoo.com&.src=ym/
5. using only XP SP2 firewall
6. using Privoxy with Tor (default configs for both)

7. description:

No such domain
Your request for http://mail.yahoo.com&.src=ym/ could not be fulfilled, because the domain name mail.yahoo.com&.src=ym could not be resolved. 

This is often a temporary failure, so you might just try again.

Below is a sample Yahoo mail logout URL, where I replaced alphanumeric
characters in alpahumeric only character sequences with "A" and numeric
characters in numeric only character sequences with "N". For some clarity,
I present two versions of sampled URLs, one having the char sequences
contracted to "Ax" and "Ny" forms, where x and y are the number of times a
(not certain) alphanumeric character and numeric character respectively
occur.

http://us.ard.yahoo.com/SIG=AAAAAAAAA/M=NNNNNN.NNNNNNN.NNNNNNN.NNNNNNN/D=mail/S=NNNNNNNNN:HEADR/Y=YAHOO/EXP=NNNNNNNNNN/A=NNNNNNN/R=N/SIG=AAAAAAAAA/*http://login.yahoo.com/config/login?logout=1&.done=http://mail.yahoo.com&.src=ym&.intl=us

http://us.ard.yahoo.com/SIG=A9/M=N6.N7.N7.N7/D=mail/S=N9:HEADR/Y=YAHOO/EXP=N10/A=N7/R=N/SIG=A9/*http://login.yahoo.com/config/login?logout=1&.done=http://mail.yahoo.com&.src=ym&.intl=us

The first url string might break the page layout, sorry if it does.

However, the browser should reach the following url:

http://login.yahoo.com/config/login?logout=1&.done=http://mail.yahoo.com&.src=ym&.intl=us

if nothing interferes, but with the mentioned rule enabled it reaches:

http://mail.yahoo.com&.src=ym&.intl=us/

which is actually the last valid url, just what +fast-redirects is
designed to get. Of course, privoxy's response is triggered by the
ard.yahoo.com part int the logout url.

Commentig out this rule might help, until a solution using regex's is
found:
{+fast-redirects{check-decoded-url} -block}
.*rd.yahoo.com/

Invalid URLs like this can be the result of Privoxy's
fast-redirects{} action. The redirect isn't detected
correctly if it isn't the last parameter (I believe
it's also mentioned in the manual).

If we knew the original URL that caused the redirect
we could fix this with +redirect{pcrs command}
(currently available in CVS only).

Where are you getting that domain? Clicking on something? It is not a
valid domain name. Try with a / after the .com part. There should also be a
"?" there to signfiy the end of the domain/filepath and the beginning of
parameters. This might be a case where a browser ingores the error, but
Privoxy doesn't.
