More questions

Well, with my previous problem fixed(I forgot to update the shortcut for
the new installation, so it was running the old version instead of the
new one); some more questions came up:

    Can people hack my Pi3Web and get access to my hard drive?  This
would be terrible because I have no way to keep backups, and have some
very, very important data.
    Also:  can I set up POP3 accounts that would go to my server?  I'm
not on 24/7, and that could be a problem.  Is there any way around not
being on at all times when talking about POP3s?  Whether or not there is
a way around it, how do I set them up?

Answers,  comments, etc. are greatly appreciated.
