Dennis D.

 

"I'm trying out ESATInformer. It's a great product, and I've had lots of positive feedback from my users."

Jim G.

 

"That ESAT program looks really nice, and I think would make for a great complement to theXWall software. I'll read up on it a little more and most likely will make the purchase of that for my company. You have a great product, and I appreciate the quick turnaround of answers to all of my questions."

Larry B.

 

"ESATInformer is a great enhancement to XWall. I feel like the guy in the 'sharpening the saw' story that Steven
Covey writes about in his book. I have been so busy that I didn't take time to look at ESATInformer before this week. I should have done it much sooner."

Tom J.

 

"Huzzah!
Dave and Peter—Count us among your friends on the Web. I know I recommend XWall whenever I can, but I don't want you guys to be too successful, if you know what I mean. Having this kind of access to the developers is priceless!

Just promise us you won't turn into Faceless Megacorp, Inc. when the word gets out about XWall and ESAT.

J.W.

 

"Thank you XWall.
It has been a few months since I checked in on the forums. Looks like things are still going good for you guys here. I just wanted to post a little update to Peter and Michael and the rest of the crew on how things are going with our install. I have offically achieved my goal of catching 90%+ of everyone's spam in my company. Most people are at 98%. With some aggressive filtering and whitelisting, we have made our goal, and the users rejoiced. We could have never done it without the ESATI package and all the hard work you guys did to help us get it converted over to work with Lotus Notes. I am still waiting to see a write-up in Network World for you guys promoting XWall/ESAT as the next 'Killer App.' You guys deserve it. Thanks again guys."

XWall fights current spam issues

BACKSCATTER Blocking.

Xwall successfully blocks fake none delivery receipts and system messages in it's current Beta release. You can download the Beta from our support site http://support.ceratec.net and install the files in your current XWall folder.

ECARD VARIANT welcome letter.

The first variant of the Ecard Zombie showed up in my Inbox today. It thanks you for signing up and includes a link to a website .... bad news of course. But there is good news. Your current Xwall (3.29+) can block the ip address. Add a string http://#.#.#.# in admin-> option-> blocking-> html

ECARD greeting card spam is presenting new issues.

Some Ecard messages are downloading zombie viruses by just opening the message. What makes it worse currently the virus is undetectable by most virus scanner. We recommend that you add subject blocks in XWall for words like ecard, postcard, greetingcard, school-mate, familymember, class-mate and so on. Many of these fake ecard messages are caught already by the CCS, SLS and SURBL filters.

PDF the latest spam vehicle It seems the spamers figured out that you consider PDF as save to pass through your spam filter. You can't just block PDF's or you loose invoices, documents and other things typically emailed as PDF. The PDF issue is addresses in the current XWall beta releases and you find additional help in the forum under Image Spam.

Compatibility

The XWall spam filter is compatible with all professional versions of Windows and Windows servers including the 2008 releases and the Microsoft Small Business edition servers series with 32bit or 64 bit core. XWall may also be used with Notes, Groupwise and other non-Windows environments. This however requires that XWall is installed on a separate machine running Windows.

XWall supports all versions of Microsoft Exchange Server including 5.0, 5.5, 2000, 2003, 2007 and 2010. XWall can be installed on the same machine as Exchange or on a separate system. The system can be inside or outside your network. Often XWall is used as a SMTP firewall in the DMZ. XWall supports SMTP mail servers including Lotus Notes, Novell Groupwise, Imail and many others.

Application

The XWall email spam filter is found in situations ranging from a handful of users to large scale cluster servers handling 15,000+ mail accounts. A single XWall server often filters the mail for an entire school district or university. The licensing is per server based. One Exchange server requires one XWall license.

A special XWall ISP is available to ISPs and ISP-like operations. It allows filtering all email for the ISP and forwarding it to multiple servers located at the ISP.

Installation

The XWall setup is painless and does not install any plug-ins nor does it hook to your Exchange server. Xwall can be put in the mail stream or removed from it with a simple port switch. The install wizard automatically configures XWall for your system asking only a minimal number of questions.

XWall is server based, installs in front of your Exchange server and does not require any software on the client system. XWall may function as application or as service on any NT class system.

Benefits

While other spam filters may also filter the mail in front of exchange they send it right to it after filtering it. You still end up with all the headaches and capacity issues. XWall with the ESAT option keeps all the spam outside your Exchange or SMTP mail server. Yet the users are informed about any blocked email and can retrieve it. This feature is available for all mail systems and not limited to some versions of Exchange. The spam gets automatically deleted after a preset (by you) time.

Components

Xwall features a long list of filter and mail handling components. It's not just all about spam. Xwall offers features like outgoing e-mail disclaimers, outgoing e-mail encryption and signing. Read more

Automation

We feel that while spam may be fascinating to some, you probably have better things to do. XWall features a great number of automated filters and features. XWall offers SLS, RBL, SURBL, Heuristic (a.k.a. Spamassasin) Bayes, Greylisting, Phishing, White list SLS, SPF, CCS (Central Checksum Service), Country block by IP, auto white listing for individuals or company wide, auto disclaimer, auto encription and auto retrieval. XWall can automatically archive all in and outgoing emails.

Support & Updates

Support is available via toll free phone to all Ceratec customers. We also offer a helpdesk, email and our busy XWall.US Forum. We also offer a large FAQ section and the right answer is never far away, including any pre-sales question you may have.

The CCS (Central Checksum Service) is an annual paid subscription service. The cost is $99.00

Software or Hardware

XWall is available as a hardware or software solution. It can reside on your exchange server or most windows-based mail servers. Or you can run Xwall on its own box which allows you to operate cross platform with almost any mail server.

If you've just had it with spam and have no time to implement XWall yourself, Ceratec offers a turnkey hardware solution.
