As part of the OPTIONS in the Barracuda you can filter on the message contents which the unit will only get after receiving the body of the message. At this point the mail has been delivered as far as the sending party.
Smart spam these days will do a good job of sending from an address that has a valid SPF and will have a subject that is not easy to catch.
End users don't like spam, and if you have email archiving policies and users under a mailbox quota you don't want to be processing all this SPAM and storing it.
The Barracuda allows you to Block,TAG, Quarantine or just turn off the filters that happen after delivery. AGAIN it is a full tool set that is up to the admin to configure correctly. The initial filters that happen at the IP and header filter WILL reject the message with the correct error code to the sending server.
I don't know about the past but the current recommended and default setting is Not to send and even if they do an SPF check on the sender is also a default option.
So if you have a published SPF record you should not be getting backscatter from a Barracuda unless they have a bad admin.
Some times experience has nothing to do with it, it comes down to time. If your organization has the budget to allow an admin the time to constantly maintain a custom multi application open source filtering system, good for them, a custom solution will always work better however I am not sure how many organizations allow for this level of staffing these days.
The Barracuda is a tool box, what you decide to do with it is up to you. The big benefit is that Barracuda maintains all the internal workings of the solutions for you and pushes them out as firmware updates.
The Barracuda bundles 12 layers of filtering that you can turn on and off at will. If you don't like the message body filters that only act after the message has been receive, ether tag the messages and deliver, quarantine or don't us the feature. \
In response to some other posts I have seen here. Backscatter is an result of an administrators decisions not necessarily the core function of a device.
As far as cost goes it is actually one of the cheapest solutions as far as bundled appliances with enterprise support go.
Of the DNSBLs and RHSBLs, spamhaus is the only provider bundled with the solution other than Barracuda's own RBL. Despite what is still listed on the Spamhaus site it is my understanding that they have kissed and made up coming to an understanding.
Any other RBLs you add are up to you to do ethically, just as if you were to apply them to your own home brew MTA solution. Donate or don't ad them, it is as simple as that.
You get 3000 to 6000 spam a day, unfiltered and you are telling me it only takes you four to seven minutes to process it all manually?
You ether get very obvious spam or are a spam processing machine.
I find the spam that each individual gets tends to be very unique in our system. Sure some you can dismiss by the sender or subject alone but we are increasingly seeing messages that are hard to spot off the bat.
I really wish more organizations would use SPF and DomainKeys correctly so that spoofed senders were not as much of an issue.
Really? Do you have any idea the resources this would take for some organizations?
Based on stats from my frontend SPAM filters 80 - 90% of ALL mail receive in a day is SPAM.
On my reports some individual users are targeted with between 1500 and 2000 SPAM messages a day. There storage quotas would probably be exceeded over night from SPAM alone.
I would need to increase my storage capacity immensely if I allowed every spam message to get to the users Junk folder. Not to mention the extra bandwidth of allowing all those mail delivery connections to complete OR to send NDRs to forged senders that are going to bounce back at my system and cause even more load.

NVIDIA To Buy AGEIA
·
· Score: 2, Interesting
A year ago both Nvidia and ATI/AMD both showed off their GPUs doing HAVOK acceleration equal or better than AGEIA. With ATI claiming to have a 7 month lead... Could this be a catchup move of patent grab by NVIDIA?
O they do try to stop it.. Every revision of the DS has had changes to make it harder to alter.. However the moders have found ways around every change so far.
I wouldn't worry about ATI/AMD not having DX10 hardware until their is content and a significant number of users that can use it.
1. You need a Game that supports DirectX 10, how many have been released so far? 2. You need the user to be running Windows Vista to have support for DirectX 10 3. The user needs to have also purchase a DirectX 10 graphics card to complete the loop.
It is the chicken and the egg, and history hasn't been kind to the early adopters of graphics cards that are the FIRST to implement a new API.
As long as the video was re encoded once that would be enough to stump simple hashing. Same goes for the same show recored from two sources using different hardware. There would be a great deal of variance.
One interesting thing to use, might be the audio track as audio fingerprinting has been around for a while now. Just search the audio track for the theme song and presto you have a possible way to flag files.
360 uses laptop size 2.5" drives. I believe the LOWEST price in USD I have seen is $109 for a bare OEM drive, tack on the cost of the enclosure, transfer cable and software update to support transferring files and it adds up.
I agree they must be replaced ASAP. However I don't keep drives on hand when my vendor can get a new disk to my desk within 4 hours of my call at no charge.
Those Deathstars as I like to call them where really really bad. If you build your servers with a strong support contract from your vendor you can get really fast drive replacement times. We run completely on Dell servers with GOLD level support. I had a drive fail in my primarily file server, I had a replacement drive on my reception desk in 4 hours from putting my phone down to report the problem. The controller supported background rebuilding so the users didn't even feel the loss.
I you build your own servers, you need to have more spares on hand than 1
More than a Year that is for sure, but some of use where only able to implement it recently corporate wide because the High uptime front end needs to be update before the back end servers can be.
We have had several users running between 2 and 7GB mailboxes. There wasn't much problem with this as long as you don't have too many users in the same message store. Very few users use that much, most of our users keep their mailbox almost empty or in the.5 GB range.
I hate that when I am over at other peoples houses. I flick the switch on... nothing flick it off.. think to my self, wait maybe it is a cheapo CF, turn it back on a wait.
In my last place I replaced all of the lights and noticed significant differences between brands and styles.
Accept that some apps and library's need to be recompiled. Which means you need to always keep a copy of the latest headers, and a compiler on your system. As well as pray the app your using compiles nicely.

It may not have the same MAX strength gain but:
a) doesn't still require a tether
b) has a much lower profile
c) You can already RENT IT.

Who is your hardware vendor? Out of the box ESX ran on both the server and the SAN we where using with NO extra drivers.
The cost is TIME and system resources, not money. Using a secure erase method takes both, as opposed to unlinking a file.

I think Cacti is the only one listed that has a reasonable install learning curve. Everything else requires deep investment in setup.
For a smaller operation or smaller feature set needs I really like Cacti.
