Spam coming to Outlook client from Comcast hosted Exchagne

to2007

We use our Comcast High Speed Business inernet account to host our email on thier shared Exchange servers.   We use both Outlook 2007 and 2010 to access the Comcast servers. Comcast tells me they really don't do any spamfiltering. Everything flows through to the Outlook clients

A couple of people are getting 50-70 junk mails a day. We set thier Outlook junk mail settings to high and now it catches about 10 or so and the rest flow to the in box still.    

I have seen that there are free spam filters but not sure how well they work.  ALso the people getting the spam/junk mail are getting it on office workstation Outlook and on notebook Outlook they travel with and on Iphone. So i assume that if there is some app we have to install on the workstation it has to go on any computer that has Outlook and is getting the emails passed thorugh, including the silly Iphone.

Problem is since it is shared Excahgne the Outlook cleint goes right out to internet to Comcast Exchagne servers and gets the email so not sure how to put an app inbetween.

I told them that they are maybe just sol and somehow they signed up for or got on a list and now just can't stop it.

Any ideas, what am i missing ???

THanks

Normally you would filter the spam *before* it hits the Exchange server, so I'm surprised Comcast is not doing that. I guess its their bandwidth to waste.

Anyway, there are a few anti-spam plugins for Outlook around:

A popular option, depending on how many users you have is to use GMail as the filter. You set up a gmail account for the user and pull their mail into gmail from Comcast. This will filter it. Then you pull the mail from Gmail to your Outlook client. Bear in mind that a "free" solution is not always the best solution.

THanks

we have about 20 some email users.

Unforutnately some of the ones listed in the first linkhave som cons taht may be too much to deal with. Plus many don't ahve any user reviews.  We have an unsophisticated user base and they cant deal with much chagne and tech thought :(    ALso some old compouters much to my dismay,

The gamil optin doesn't look good as Comcast wopn't let you at thier servers to redirect. Also i am kind of not the biggest fan of gmail goolge .  THe setup evne if Comcast let us at servers looks like a problem waiting to happen in our office.

My solution is replace toh old Windows 2003 DC server with a Windows 2001 SBS server and get the darn email in house. then we have more control and can use the add ons for Symantec End Point the we have in house with the Exchange Server in SBS.

Any thoughts on this?

thanks again for the respsonse.

Compare the cost of getting email inhouse versus outsourcing it. The biggest advantage of having it inhouse is that you can control your anti-spam at the front end before it even gets to Exchange (which means you use less bandwidth, and less storage in Exchange). My office uses Mcafee for antispam, but there are lots of solutions. As you mentioned, you could also use the Symantec solution on your SBS server, but that means additional load on the server. Not sure if that would be the best solution, but if it is cost effective for you, it would work almost as well as a third party filter, you just don't get the bandwidth savings.

ok

so there really is not simple solutin since we can't point the mail at a spam filter prior to the Comcast Exchange servers.

we either get third party apps to install in each Outlook client on network and any Outlook cleint they use remtoley that points to Comcast Email Servers and also something for thier iphones.  SOunds like a big pain and cost even if share ware to setup.

As you mentioned we can have Excahgen in house on SBS, it really isn't a huge huge cost to setup as we pain Comast about $800/year for all the emails addresses and deal with all the others issues of file size and storage on thier servers and backups.  then we can run the mail torugh a Barracuda spam filter or something at an ooutside isp etc berfore it hots the Exchange.

How much load do you think it puts on the band width and server if we have the Exchange in house on SBS 2011 and don't run through outside spam service fist and use SYmnatec EP and or Macafee?

we have would have the server setup with 600GB to qa TB of space and 16 GB of RAM.  The Comcast business internet connection runs at about 15GB down and 6GB up.

If you filter the email using a separate device, such as the Barracuda you suggested, the traffic won't be that great. Using an outside anti-spam service will have the same effect, but obviously you don't own the equipment. Either way, eliminating the spam before the server will save you storage and bandwidth. Certainly storage of the legitimate mail will be the same either way. I have run 100+ user companies on a 3Gb connection. So you will be fine.

I suppose if you have any concern about the volume of email taking away from your internet bandwidth, you could always enable QoS on your firewall and give email a lower priority.
