All these things that I have done

I have one on my own server (very basic and bare-bones - it's just for viewing what's on the POP server while you're on the road - you can reply or delete or leave it there for downloading once you get home). It's only http not https, so I don't know whether that's more or less safe on the face of things. (The transmission protocols themselves are not my strongest point, stupidly enough for a sysadmin). That said, there are more advanced ones here.
