Sure, Clinton sucks, but the big knock against her and her email server was that she wasn't secure enough with it.
My quibble was the blatant arrogance of the act. That private server was clearly a move to preserve final editing rights of her tenure at the State Department and evade any future FOIA requests that may crop up during her next run for the presidency; and was there ever any doubt that she would run again? The fact that she thought she could get away with it after experiencing the fallout from the exact same move by members of the Bush administration while she was a sitting Senator in Washington reinforces the feeling that her arrogance knows no bounds. She took a page out of the neocon playbook and figured she would show them how it's done.
