Alternative to DSPam

Since dspam is causing so many problems, why can’t we find something better?

Too much money invested would be the likely reason. However, can we bypass DSPAM ourselves, so that it is optional. My $3/mo Cloudmark account worked just fine.

If DSPAM doesn’t prove to work right for us, we will swap it out for a new system, regardless of how much money we have invested in it

Unfortunately, We’ve been getting complaints from most of our clients since DSPAM was implemented as well.

What are the possible alternatives?
