Collisions with mesh colliders should work. However keep in mind that mesh colliders are not "solid", they're paper-thin surfaces. So if a particle ends up inside a mesh collider due to tunneling it will not be projected back out. Depending on your use case, distance fields might be a better option. See:

As I mentioned, MeshColliders are not solid. If you suddenly change the scale of the collider, chances are particles that were outside of it before the scale change will now be inside. This is a form of tunneling. You can get a better idea of what's happening by adding a ObiParticleRenderer to your cloth to see individual particles.
