Merhaba Arkadaşlar
Exhange Server 2010 üzerinde kota olarak 4mb kotası koydum ama gönderilen maillerde exe,excel vs uzantılı dosyaları kısmen nasıl engelliyebilirim
İlk exchange kurulumum olduğundan tam yetkin değilim ama her şey düzgün ilerlemekte sistemde exstra güvenlik anlamında bir kaç düzenlemeye daha gitmeyi uygun gördüm ama konu hakkında fazla etkin değilim yardımcı olabilecek arkadaşlara şimdiden teşekkürler.

We are going to create two different rules.
- Rule # 1: Since .zip files are sometimes used to encrypt legitimate data, we want to make sure that we let the sender know that we do not accept these types of files by rejecting them with an NDR (non-delivery reply). This way, they are not left thinking that their e-mail has reached the intended recipient.
- Rule # 2: Since the rest of the files listed are usually viral in nature when sent through E-mail, we are going to reject those without notification.
Open Exchange Management Console and navigate to Organization Configuration > Hub Transport and click on the Transport Rules tab.
Rule # 1: Block ZIP Files and Notify the Sender that their ZIP File was Blocked by Exchange
Click on New Transport Rule in the Actions pane. Give the transport rule a friendly name.
In the conditions step 1, select 'when any attachment file name matches text patterns' and then click the text patterns link in step 2.
Type .zip in the text patterns field, click on the green + sign to add the text and then click next.
In Actions step 1, select 'send rejection message to sender with enhanced status code' then click on the rejection message link in step 2.
Write a brief bounce back message then click on the enhanced status code link.
Specify an NDR Code; use either 5.7.1 or any value from 5.7.10 – 5.7.999.
Click next. The next section is an exception rule. If you want certain people to be able to send you zip files, this is where you can create an exception rule. I like to use 'when the subject field contains specific words'. This allows me to give legitimate zip file senders a sort of 'secret code word' that they can insert in the subject line to get their zip files trough!
Finally, click on the new button to create the rule.
Finished, now let's create the second rule.
Rule # 2: Block Malicious Files without Notification
Rule number two will not notify the sender of the rejection since most of the files we are going to exclude will come from spammers.
Once again, click on New Transport Rule in the actions pane.
Give your transport rule a friendly name.
Click 'when any attachment file name matches text patterns' in step 1 and then click the text patters link in step 2.
Complete your blacklist of attachment extensions by entering one by one.
When finished, click next. In actions step 1, click on 'delete the message without notifying anyone' or any other action you find appropriate.
Create exceptions to the rule (if you like) and then click finish. The rules should take effect immediately.
