If you're worried about viruses use another POP or IMAP client with Exchange server. Who cares about the client anyway. The strength of Exchange server is keeping all email in a database and greatly easing administration compared to a regular POP server. Even Oracle is going to that model because it's the way to go.
If you want to improve the performance of your Exchange server dump NAV. It uses the old MAPI API. Basically it creates a maibox with admin rights that logs onto other users' mailboxes and scans for viruses. It's a memory hog.
A better solution is called an ESE API anti-virus program. Sybari's Antigen was the first to do it. They hacked MS Exchange to do it. I forgot the specifics but I'm pretty sure they use the back up software API calls to do online virus scanning. The software sits outside the IS and scans messages before they enter the Information Store. And it uses a lot less resources. We use Trend Micro Scanmail 3.61 and it works great. MS tried to improve things with AVAPI, but the ESE is still the best. And with Scanmail you can even block attachments by file type.
And as far as my post, for a small office it makes economic sense to deploy Linux. The Global Address Book isn't an issue along with other features of exchange. But as the size of your organization grows you need to have a total messaging solution and keep everything centralized. My company has over 600 people and I can't imagine everyone needing to keep an address book to email other people in the company.
I'm sorry but 100GB hard drives don't cost $200 in SCSI mode. Try close to $1000. The whole point of Exchange that makes it attractive is that you centralize everything including the email messages on the server. Once you configure it properly which is pretty easy there is almost no maintenance except adding user accounts.
Service packs come out once a year. Trend Micro scanmail for exchange updates itself automatically without reboots. And it's a great anti-virus program that catches viruses before a user opens them in outlook. In fact it catches them before they hit the Information Store where all the email resides.
No. All the attachements are stored in a separate table. With individual email messages it most likely happened already since all the little one line answers and replies that get sent out as a result of each message.
But which software do you run on the server side? With Exchange all the email in a database file and you get single instance storage to save space. The user directory is in another database. Exchange is almost like a slimmed down SQL server. Even Oracle is going to this model for their new email server because it's awesome. Only time we touch our exchange servers is to add users.
Since it's a database you have option called deleted item retention time. When a user deletes an email it stays hidden in the database for whatever amount of time you specify. If you have the storage it could be months or years. If someone deletes an email message restoration takes seconds from the client PC. Exchange 2000 takes it one step further to the mailbox level. If you delete a mailbox by accident or after a termination, you can restore the mailbox with all contents.
Backup is easy. And Veritas even has an option called brick level back up which backs up the mailboxes individually. A company called Commvault takes this to a new level and can back up single messages. If you CEO deletes an email you just restore the message. If you delete a mailbox and someone needs it you just restore the single mailbox.
Is there anything that runs on Unix or Linux that supports these features? On an enterprise level they are a requirement.
We're on NT and it's the same thing. All of our developers and telecommunications people don't have any problems. All the HR and other admin people can barely type their password in without help. Linux isn't going to help.
For mail you can setup Exchange as an IMAP server and a linux desktop as an IMAP client. You will lose the address book feature so it's worthless except for while travelling.
This is OK for a small office, but what about a larger company? Many companies have deployed MS Exchange server partly because of the integrated global address list and the fact that you can store the email in a central database instead of downloading it to the PC like a POP3 server. Is there a Linux based mail server with these features?
I only saw the trailers but it doesn't seem very realistic. Americans never leave their dead or missing on the battlefield. Not after Vietnam. When I was in the army we were taught that we should risk our own lives to bring back the bodies of our dead. To the US Army Rangers it's a part of life. Somalia is an example. Same thing with missing. You search for them until you are sure they are dead and then you bring back the remains.
But it's a good story for Hollywood about a rogue officer trying to do what is right and going against the beauracracy. Americans hate beauracracy and it reflects in our art.
What if I decide to market a new device that runs on the same frequency? And I decide I don't care about working with Verizon, MCI or anyone else if my device interferes with their service? I guess you won't be talking on your cell phone very much.
Remember in the DOS days when developers could write apps that took resources and never gave them back? Remember 100 years ago before the FDA people would sell colored water and pass it off as medicine? Or no regulation in food quality?
But you using Opera won't screw up someone else's made for IE-only website. Where if some joker makes a wireless LAN device running on the same frequency as your cell phone, then guess what. You'll call your wireless carrier and they will tell you it's the other rogue devices on their spectrum that deprive you from using your phone. You call the company that makes the wireless LAN device and they tell you to go screw yourself. They will say since no one controls it they have as much a right to the frequency as your wireless carrier. And you get chaos.
What if someone decided to make a device that used the same frequencies as directTV? It might tick off a few users. So think about the real world next time you decide everything should be free and no one should control anything.
If there was no control of the airwaves then we will have device manufacturers using whatever frequencies they wish. Then the question of interference comes up. What if Verizon and MCI tried to grab the same frequency to market their latest wireless service in the same location? And what if that same frequency was in use by someone else's device? Who would be the final arbiter in these situations?
In my experience working for the US government I have never seen them use a private IP range. They would have Class B subnets and use only a fraction of the available IP's. The rest are pretty much wasted. So if you can't beat them, join them. Become a government agency and you'll have all the IP's you could want.
CCNA you only need to read the books. Check the web for practice tests. CCNA is only very basic stuff. I did mine in a month without touching a router. Sybex sells a study guide with a virtual router program that I can't recall the name of. After CCNA go get a job. No point in getting an advanced cert like CCNP without experience.
You will be branded a terrorist just for knowing this information. Everyone knows Americans are supposed to be stupid and not know anything except for sports. Why would anyone need to know how to spoof your ISP and the DoJ who want to watch you?
I got out of the US Army last year and my last duty station was in Italy. I worked at the General Staff level and used my government credit card to pay for many dinners with visiting VIP. Imagine my surprise when paying for a dinner the restaurant owner brought out a wireless credit card machine. And this was a year and a half ago.
I've read a few articles in the last 6 months about how a lot of techies in California are going to work for porn companies. After being laid off they are finding jobs in the porn industry doing sys admin and programming jobs.
I read an article a few months ago and it said that the government is involved in this. The national labs have engineers from intel, amd and other companies and government scientists researching these new technologies. The technology will be out in the open and no one company should own it.
That's what they said about the Voodoo2, the P2 chips and almost every new cpu that comes out. Until a game I play has real time 3d graphics that are totally lifelike we're not there yet. And I mean every little pore on the characters faces is individually bump mapped and rendered and real arm movement.
The enviroments still look crappy. It's just large polygons with painted edges. And were no where near enviroments that react realistically to your actions.

A good anti-virus program like Scanmail from Trend Micro based on the ESE API will stop any virus before it enters any of the mailboxes.

As far as I know that was with the retail version. Couldn't resell the OEM version.

I have MS Messanger on constantly and down time is so rare I can't remember the last time it happened.

Well the pre-rendered cut scenes look pretty goo now. How about making in game graphics as good as the cutscenes.
That's weird. It works fine on my windows 2000 box. And I thought it was windows that was supposed to be unstable and linux perfectly stable.
That's what they said about the Voodoo2, the P2 chips and almost every new cpu that comes out. Until a game I play has real time 3d graphics that are totally lifelike we're not there yet.

The enviroments still look crappy. It's just large polygons with painted edges. And were no where near enviroments that react realistically to your actions.
Maybe they were looking to make Hercules in space?
