Groupwise 6.5 Spam Filtering

[hughesjm]

We will be upgrading to Groupwise 6.5 soon and I was wondering if there are any 3rd party spam filtering applications that will run with it? We are currently running 5.2 and the spam for many of our users is out of control.

According to my sources, spam filtering is a feature that will be included in the new version of GroupWise.

We are currently testing a few different spam filtering software packages. So far the one I have been impressed with was from SurfControl. They have a good price and a simple interface to use. The software sits on another box and forwards incoming mail to my GWIA after it has been filtered through the predefined rules.

As with all spam filtering software, run it in test mode for a month before you enable it. It does filter out wanted mail from customers if you just enable it and leave it.

I have been using GWgaurdian for several months now. We have approx. 800 users and have seen dramatic decrease in spam, also the Virus' that make it to our antiviral software are almost nile. Its not cheap (2k+) but the volume of bad mail it has stopped has made it worth every penny. You can find the trial version and documentation at gwtools.com.

Another method of SPAM filtering you might consider is a SPAM ASP. Spammers are quite clever, and to outsmart them you need a SPAM filter that has some intelligence or is close monitored. For example, your software might catch VIAGRA, but will it catch V*I*A*G*R*A ?? The recent Groupwise Advisor Forum in Los Angeles showcased a number of anti-SPAM software and providers. You redirect your MX record to these services, then they filter your e-mail and send legitimate messages to your e-mail server. I'll follow up with a vendor name in my next post.

There are several, such as quinivere and gwava however most depend on keyword or domain filtering which is ineffective against SPAM. We just went with a ASP service from Mailwise a division of DWS, the largest GW VAR in the world. We were filtering 15% of our mail internally, we are getting 65% with Mailwise or about 97% of our SPAM. It is $1-1.50 per user/monthe, well worth it.

Guinevere with SpamAssassin installed is wonderful for stopping SPAM.

We have been using 6.5 for a couple weeks now and the "Junk Mail" feature does work for spam. But with the new features such as the catagories and filtering, I think that this could be a powerful tool.

Will need more time to work with it.

for spam control we've been using Mailsweeper for SMTP for many years now and have been pretty happy with it. It's an SMTP proxy that sits between the GWIA and the internet. It works with 3rd party AV vendors (Sophos, etc) and you can work up some pretty fancy routing and rules wrt an email 'policy'. One great feature they don't seem to advertise much is that the product is licensed per user - they do not care how many servers it runs on. So, I have 3 email proxies.. 1 dedicated inbound, 1 out (and backup in) and a 3rd one that can jump in the fray if needbe.
Stopping spam is getting harder and harder though with folks sending links etc so we distributed some of the workload onto our beloved users by giving them GW6.5.
Just installed it this past Friday night and so far we like it better than 6.0 and a whole lot better than 5.5! you can junk or block by address or domain or use a whitelist.
sweeeet!

I'll add a vote for SpamAssassin (

http://www.spamassassin.org).

No cost, and it's working great for us, catching around 97-98% of the spam.
