Listing

• BlackSpider relay service (JustinMason: do BlackSpider use SpamAssassin? There's no indication on their website that they do.)

• Bastion Mail relay service based on Spam Assassin and Mail Scanner.

• MessageLabs relay service (JustinMason: do MessageLabs still use SA in their system? I don't think they do, any more.)

• GMX (free)mail service (they once definitely used SpamAssassin and it feels like they still do, at least in parts)
