No... a closed source program would be ok... but the rest of the operating system is part of the DRM chain and it could never be considered a "safe pathway".
I'm italian and i followed the story with much interest. Unfortunately news lacked important details about phenomenons, when and how they happened and expecially which of them were true.
If it was an EMP so strong to burn power lines, why didn't it fry all the small electronics (including scientist's instruments) which are more susceptible to EM fields?
it's using a different method of dealing with the problem...
I see your point. I cited SpamAssassin just because I like it and it very effective.
I can imagine the approach MS is taking with regard to the SPAM. I can foresee some proprietary extension, with obvious problems that will never become standard and will be another hassle for us poor admins.
If you aren't using any of the "Don't Blame Sendmail" options of sendmail, it can be just as secure as Postfix...
Ok, it's clear that I'm a big fan of Postfix, but you have to believe me that my vision is not biased. Being secure is not matter of not knowing any vulnerability, it's a matter of knowing that a vulnerability in many parts of it will not result in major problems. Most of the daemons comprising Postfix run unprivileged and chrooted and communicate with the others thru pipes. This makes it more secure because this is a more secure design.
but blaming the current sendmail for things that happened years ago is just plain wrong...
I blame current sendmail because it is more prone to have major vulnerabilities, regardless of the past experiences.
Really??? What's your UNIX distribution??? Solaris??? AIX??? HP-UX???
You know I was talking of Linux... and... until SCO is proved wrong, it is UNIX:)
In such systems, backward compatibility is often more important than other issues so they tend to remain stuck to sendmail and other "legacy" software.
Well, lets see...spamassassin works with sendmail, so I don't get your point there
Simple:
Postfix is better than Sendmail.
Spamassassin is better than anything Microsoft may even thing to write.
Two orthogonal concepts.
And, as far as postfix being better than sendmail...sendmail has a bad rap because it has been around the longest...
You may not have looked at Postfix deeply enought. Postfix is better in the way it is designed and in the way it is implemented. The multi-daemon design is orders of magnitude more secure than anything so monolitic as sendmail.
The code quality is spectacular. I had to customize it a bit and the sources was so well written that I was able to understand them almost immediately.
Yes, some older versions of sendmail had security problems. Yes, sendmail has some feature bloat...
Those security problems could have been cosmetic issues in a design like postfix's.
But, sendmail is the MTA of choice for UNIX distributions
Not anymore for my distribution. Anyway, this doesn't mean it is better... for the same reason Windows is installed on most computers...

What makes Linux and its software (generally) more secure is the design and the security consciousness of its developers.
We all know that Lunux's TCO is often lower than windows' but one shouldn't count on the absence of worms.

Hey, RS-232 is not the only transmission encoding system :)
Sigh... I was writing the exact same thing :)
Oops... I reread your message and now it's more clear. 0.07% is calculated on yesterday statistics, 5 false negatives on 7000 spams received.
0.07% are false negatives, spam messages that are not marked as spam.
False positives (legitimate messages that are marked as spam) are virtually inexistant.
The bump was caused mainly by some stupid spammer who tryied to guess local names at my domain not understanding that I have a catch-all configured :)
Even excluding them, I still noticed an increase in spam traffic in the last week.
97.4% of all e-mail received at my e-mail address this week has been SPAM.
I receive an average of 1100 SPAMs/day but in the last two days the flow bumped to more than 5000 SPAMs/day.
Luckily, my installation of SpamAssassin has a false-negatives ratio of 0.07%. Nice uh? :)
Graphs are available at http://www.orlandi.com/gimme_more.php, sorry for the italian text, tought the meaning of the graphs should be clear.
I saw a traffic light working exactly as described in Italy more than 8 years ago in a mountain locality.
It was tuned to become red if the speed of the car approaching was more than the 50 Km/h allowed in the town.
It has a strong psycologic effect
"...enough power from tidal waves to service 10,000 homes..."
...and how many human hairs is it big?

Stronger gravity means that the escape speed is higher so even the lighter gases need to be warmer to escape from the planet's gravitational field.
At the end, the kind of gases that could be retained depends on their weight AND the strength of the gravitational field.

Could this be a sign of the beginning of the end of spam?
Dunno... but it could be the beginning of the end of sendmail. Not that it would be a bad thing...
There's much better software out there.
Hobbits have remarkably white teeth considering the lack of modern dental equipment in the shire. It's funny to hear that by someone modded Troll :)
So, what's the difference between "undefined" and "no value" ?
To me a variable without value is undefined and an undefined variable doesnt' have a value... but I could be wrong...
Mmmh... NULLs and "maybe" have totally different meaning... NULL is more "don't have a value"
Yup... I should have known... damned Euro... I want my Liras back!
Actually, putting 6 zeroes after my negative bank account would be anything except a deterrent for suicide :)
Yes, you're right.
I hope you're not the same AC I answered few minutes ago... eventullay you're discovering the difference between winners and loosers (you).
