Exchange Server block attachments

Running Exchange server 2003 and need to block exe, zip (fakes) before the email hits the exchange mailbox.

What should I do.

Also would your suggested solution work on a 2013 exchange server?

Get an antivirus for your server which is Exchange aware, it will sort that crap out. Alternatively use a cloud based antispam and filtering provider which will do that in the cloud. Either way there is a cost.

Yes it will work with Exchange 2013 too.

With  newer versions (2007,2010 and 2013) you can create Tranport rules on exchange to drop the emails which the attachments.But with exchange 2003 you need to use third party spam filtering software

If you want to block the attachment like .exe, .zip etc. you can install Scan mail for Exchange software that means you need to purchase the third party spam filter software for internal. like Forefront, Trend SMEX (Scan Mail for Exchange)

if you want to block in Exchange 2007\2010\2013, you may create transport rule. so that you can avoid cost for third party SPAM Filter software.

Thanks.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

@vijayhakcers @ mboppe: Transport rule doesn't work well. If you send a Word attachment with the word zip or exe (what you configure in the transport rule) within the document it will get deleted (or actioned according to your transport rule).

Give it a go for yourself and see.

Yes. if you send mail with attachment .doc file to as zip, it will not block because there is no capability to scan the zip file. that terms called embedded, it will block direct file. if you want block that kind of files. you need to purchase exchange aware spam filtering software.


Thanks.

All Exchange antivirus products are able to do this, and get round the renamed file issue as well. I was doing this years ago when the first variants of the zip file malware started to appear. Do you have AV on the server?

I don't think Microsoft sell Exchange 2003 AV any longer, but third parties should support it. If you can, get something that is different to what you have on your desktops, so you have dual layers of protection.

Thanks for the info.
I will go to the ECP  mail rules and add rules on my 2013 server and test that.

On the 2003 I will look at 3rd party.
Currently using Vipre on Desktops.  
I see a couple recommendation in the thread any other opinions on the antimalware for exchange.

Transport is what I was looking for but with the 2003 server I'll have to use the 3rd party solution.  
Thanks for specific recommendations on av solution.
