We are a small company.  We dont run Exchange Server.  Our email comes to our donmain name, and it is all housed by hostmysite.com

The called me into his office.  He says he keeps getting email that every body wants to make his **SMURF** longer or harder.

I have been trying to help by using Outlook Filter rules the best I can.  But these SOBS  keep mis-spelling words... putting spaces in places there should not be.... they are doing things to get around the filtering.

I need help and ideas to try and cut some of this spam down.

Is his email listed on any websites? If so, you can do something like listing the email address (without a link) as username  [AT] host [DOT] com ... makes it harder for programs that scour the Internet for email addresses to capture it.

Outlook lets you filter out an entire domain, but that does not include subdomains unforunately. You could also install software such as SpamKiller (http://www.spamkiller.com)

The easiest answer would be to move to a host that provides spam blocking solutions.  Most provide them, some more effective than others.  There are hardware solutions as well such as ironmail or open source solutions like spamassassin.  User agent solutions are the least effective.  Your solution should use multiple methods for detecting spam including real time blacklists, routing, keywords, user blacklists and whitelists.  I personally use spamassassin and it features all of these.
I am having a very hard time not cracking a couple of jokes about the above statement!!  Anyway, I think your only good solution would be to buy an appliance that sits in your DMZ (internet entrance) to trap the spam.  It would be kept up to date from the manufacture and controlled by IT (you?).  Depending on the amount of users you have, it can be fairly inexpensive.  If the person that is getting email about bulking up his junk and he doesn't think he needs it, I am sure they would pay for the device...sorry...had to make one crack.

If you want help finding this device, please let me know how many users you have and what type of connection.

You can use an application like norton anti spam to filter in the email client.  I would also recomend mooving your service to another provider, register.com is one of the bests and offers spam protection.

hi mrchaos101

my company was having the same issues and we were a bit to busy to deal with this kind of issue so we hire an outside firm and trust me they are work every penny we pay $150 for incoming email filtering we have about 100 user accounts and they have been very happy because the filter removed the unwanted spam also they have snap in tools for outlook 2003 that if a spam makes it through you flag that email as spam and trust me you will not see it again. check them out

www.mxlogic.com and did i mention that to date our spam filter has stop 150 virus that were sent to our network. i love this company they have help easy the every day email reading.
I agree with Psicop, you have very limited antispam options if you don't have your own network equipment. Its impossible to set antispam rules that fit several entities. Each of them have different need and deal with different people. First thing to do is to disable any "catchall" account and remove email address (in ascii text) from your website.

Danny makes a good point if you have your email address on your website many spamers will find it and use it.  If you need an email on your website you can do as Danny suggests or, list the email as bob @ domain . com (users will beunable to click it but spammers will also be unable to find it), or do not post the email and use a contact form where a visitor can fill in there email and question and you can contact them back.

Well Im VERY NEW to the IT field. This is my first Network Admin Job.

Small network only 20 computers.   They dont want to spend any more money for now.  I have milked $7k out of them for the server and 1k per work station.  I built the network from ground up.  WAS A BLAST.  A lot of help came users of this site.....

Back on topic,  I was using outlook for the spamfiltering.  I assumed the Web host filterd out spam by default.  After reading the first post  I contacted the web hoste and got the spam filters configured.

Seems to be doing the trick.   We still have one guy  (the nasty one) getting though some how but it is better the it was.

OK if Outlooks filter is not enough for you, Symantic anti-spam is only about 30 - 50 per computer and works excelent.
