Projects which integrate SpamAssassin

This is a list of open source projects which have SpamAssassin integrated in some way.

This list should only contain open source or free-software projects. For commercial solutions, see the relevant section on the ThirdPartySoftware page.

Note for Developers

If your open-source product uses SpamAssassin, and is not listed here, please feel free to edit the page and add details.

However, keep it short here; one paragraph or so. This is a place to introduce your services. Go into details on your web pages.

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.
