Default What solutions to manage spam in a BES environment?

Please Login to Remove!

What have you done to manage SPAM in a BES environment? I use an Exchange 2003 for mail, and our users have messages filtered into the "junk mail" folder. Unfortunately, the Blackberry throws all messages into it's default view, regardless of the folder.

What have you done, if you didn't wish to spend money on any third party spam tools.

Further, if you did spend the money, what tools work best in a BES environment? The way i see it, any tool that moves messages to Outlook's "Junk Mail" folder still does not solve the problem, as the BB will still see it.

Set Hide Filed Messages to Yes.

There really is no SPAM filtering on the BES server. It is basically a forwarder. If your not blocking it at the Exchange server it will be forwarded to the BlackBerry handheld. If your performing your SPAM blocking at the client it will still be sent to the BlackBerry handheld. The BES server is watching the Exchange server, not the Outlook client.

Yes, this much is obvious d_fisher, i'm talking from a higher level perspective. People with BES installations probably had to do *something*. What did you do is the question. All suggestions are welcome.

By the way, hide filed messages -- works for users who don't filter messaged into folders. I do.. (i have 30-40 folders, 20 of which have rules to file into)

But a viable solution for some. Thanks.

We use an external spam service which works pretty well... Link--->Welcome to Postini

My organization uses MX Logic, essentially all of our email MX records point to their email servers, which filter out spam/virii/etc before forwarding them on to our 'real' incoming mail servers. We've had a few minor issues over the years, but for the most part it has been a great service. We are able to manage each email address individually with regards to blocking, quarantines, and the like, with the administration done via a Web interface. In the event that a real message gets picked off we can very easily go into the interface to find it and remove it from the quarantine. All in all a great solution (for us) although I know some organizations won't like the idea of having another company control their incoming MX flow.

We're pretty small, (250+ users) so we use symantec software to filter at the exchange server. (cheapest route) If I had my way, I would go with an appliance, such as Barracuda.

good idea would be to throw a spam filter box into the mailflow before it gets to Exchange. Typically people set up incoming mail to go through the edge transport box (sendmail or whatever) through a spam/virus scanning gateway, and then into Exchange.

On my BES mail sent to the "junk mail" folder does not get forwarded to the BlackBerry. As long as it is a server side rule, it will work fine.

You could delay the message processing of BES so that the junk mail filters can process the message out of the Inbox prior to BES picking it up. If you dont redirect your junk mail folder, BES wont redirect it to your handheld.Its a registry edit to put in place and a restart of the controller. There is a KB article on the site, kb-00139, shows you how to do it. Its worked wonders for our 13 servers here, users previously complained a ton, not anymore. I would recommend a delay between 20 and 60 seconds, but tweak it to your environment.

In this day and age, though, you're best to protect yourself and put something in front of the BES, in front of the Exchange environment. We have 10 SurfControl E-mail Filter servers for processing all inbound email to our network. It rids us of about 95-98% of all spam coming into our environment (and we process millions upon millions of email per day, so not too shabby). I'm not sure how the laws are north of the border, but if an employer here in the States does not take some sort of measures to protect their users (they really just have to show they are attempting), then they can very easily be held liable for any sort of legal action an employees seeks against the employer - this could be a number of legal issues. You aren't going to be expected to keep 100% of all spam out of the environment without affecting day-to-day operations and business, and the legal systems understand this, but you should, at the very least, attempt to do something to keep some out before it hits the end-users' machines.

I use SpamAssasin with an a rule that if the Spam Level in the header is "******" or higher, it gets sent to Junk Mail and is not redirected. This folder is not redirected to the BlackBerry.

Works well for me, and I have not had any false positives.

We use SurfControl which filters Spam before it hits the mailbox.

I'm currently using Postini, but have used MXLogic, both services have been much better to locally hosted solution I have found. Also they are pretty cheap and real easy to administer. You don't need to by another server or anything. 75 users runs about $160/month iirc. MXlogic doesnt even make you sign a contract so you can try them out.

Thanks guys, i've implemented the Registry delay. I think this will suit us just fine..

We are using Outlook 2003 client side to filter spam. Yes, it's not the best solution but it's cheapest, and it works. Not many employees have a spam problem, but those that do are getting barraged..

even fewer have a blackberry, so this is going to be just fine for now.

I cannot even get the combination of turning ON Hide Filed AND setting the delay on the server (I tried 2 full minutes.)

Am I missing something? I have both SBS 2K3 Exchange IMF and client enabled junkmail (Outlook 2003) enabled. I don't even see how client side is supposed to do anything anyway as there is no connection between Outlook and BB device?

Thanks for any tips!
