Since I see that my Linux Kernel version (2.6.19-2) does not have this entry in the /proc file system, maybe listing an example site that is unreachable will help determine if I have the problem or not!

Any chance you will list at least one unreachable site?

Cheers,
tony.

PS: Wanted to mention that I do get timeout issues when sending mail to some sites with Sendmail - could it be related?
