Note for Vendors

If your commercial product uses SpamAssassin, and is not listed here, please feel free to edit the page and add details. If it's not obvious that you use SpamAssassin then perhaps you do not want to list your product here.

However, keep it short here; one paragraph or so. This is a place to introduce your services. Go into details on your web pages. The idea here is to provide people who might want to have someone do their spam filtering for them a place to see what vendors offer.

We reserve the right to edit or even remove whatever's published here (especially if we cannot determine from publically-accessible information that the product does use SpamAssassin).

For fairness, we'd like to keep the items in each category in alphabetical order.
