Keep Spam Out Of Exchange Server

I had an interesting discussion with a number of Exchange administrators a few days ago. Your solution to spam is to configure the Exchange SPAM to get everything on a given SCL score you in the spam folder of your mailbox and allows the user to sort.

It is an interesting approach, at least the least administrative effort in the sense that never in the hunt, why an e-mail is blocked, or call for an end-user quarantine.

But like many "quick fix" solutions, he adds other problems to the composition, because the junk mail folder, part of the mailbox of the user on the Exchange Server information store.

Let us first what we know about the volume of spam on the Internet today. Most reports put it at 90-95% of all email traffic. My stats own customers back to that, we shall now is that 90% a good estimate.

I am often in the implementation planning Exchange incoming external mail accounts over 20% of email traffic.

So an organization with 100 GB of data bases mailboxes, 20 GB, the email is coming from outside the organization. If the 20 GB to only 10% of all incoming mail (or 90% of spam), the organization up to 200GB of e-mail instead of 20GB, all mail received by the access from Exchange server.

So, at this stage of the demonstration, we have an Exchange server hosted twice as many data e-mail, it seems that were it otherwise, because it is authorized to receive and all the spam e- mail storage.

Not only did it to save it to disk, it also needs to bring every night on the hard disk or on tape by the cost of storage media.

Most clients I speak at least a little sensitive, consume a large portion of the storage capacity of the Exchange server. Very few of them have to throw unlimited storage for e-mail, and most of them in memory quotas on mailboxes to manage growth.

This brings us to the next problem - all mails, leading to end-users exceed their storage limit much faster. Or you have to annoy the end user who needs more frequent cleaning, if you need the quota (and therefore to accept that any additional increase in memory load).

Outlook itself has to say no automatic cleaning options Junk e-mail, unlike the Deleted Items folder. The client is either with all the junk e-mail for real objects to check before deleting them, or simply choose to remove both (the goal for them to sort spam frustrated first) .

You can archiving problems to solve, but everything you do, the problem of displacement is to store your archive system.

I see this solution. I certainly would not advise anyone to take this approach to the management of mail for Exchange Server environments.
