In simple terms I need to find an appropriate spam filtering software for my needs.

Here is my situation.  In about a month I will be leaving to go
traveling through Asia with just a backpack for 6-9 months, so no room
for a laptop.  I run my own business and will be checking up on it
while traveling at cyber cafes which most will still be on a dial-up
connection.  So I will have no time to download the around 600 spam
emails I get in a day.

This means I need a spam filtering software to help me out.  The thing
is the filter has to be located on my hosting service that my website
is located as I will be on a different computer everyday.  As an
example I tried out SpamBlitzer which you can check out: 
http://www.scamfreezone.com/spamblitzer

It just had a few to many bugs for me but the concept of being on my
server is what is important.  I had to get my money back on it and now
am on a search for a better spam filter.

I need it to filter out the spam before I get onto a computer and
download my email.

If you could please give me a list of at least 2 (preferably more)
spam filters that fit my criteria that would be great.  Also I am not
willing to spend more than $100 and would prefer it to be under $50.

Hi,

There is only 1 solution for you, it's a company called
www.mailblocks.com, and simply the system uses a challenge/response
system to get rid of spam out of your email. It allows you to carry on
using your ISP email account but allows you to view all your emails
via a standard web browser from anywhere in the world.

Here are some links to get more information; I can honestly say that
you will not find a better service to use.

The best anti-spam program I've used is www.qurb.com, this program
learns with you and has an excellent knowledge of what is already
spam.

Thanks Catmar,

I think mailblocks looks like it is going to work for me.  I appreciate the info.

Sugart - I have friends that use qurb and think it is great but it
won't work in my situation.

Thanks again Catmar for the help.
