Fetchmail in alpine is ~5 years old — and doesn’t support current SSL/TLS variants anymore. This especially leads to our own fetchmail not being able to pull mail from mailu itself. Since no new fetchmail release is on the horizon, let’s build the lastest distribution artifact — which strangely is not 6.4.0-snapshot, but 7.0.0-alpha — ourselves.
