I doubt we can solve this for other people. Each person must solve it for themselves, but for most people the solution will be joining a church and attending weekly. From there, get involved with a ministry, that will lead to appreciation dinners, which will lead to getting invited to the non-religous stuff the people are involved with.

I wasn't able to get a response from Proofpoint directly but by complaining to Icloud support I was able to get forwarded to an individual at Proofpoint and he got me setup. Proofpoint does not care about you if you are not a customer. So you have to harass Proofpoint's customers and if they care about getting your emails they will help you out.

I think the process took 2 weeks.

EDIT: I wish there was a more professional/straightforward way
