Prefix/postfix/infix refer to the order in which you write operations and their operands—equivalently you can think of preorder/postorder/inorder traversals of the syntax tree.

    AST          +
                / \
               *   5
              / \
             2   3

    Infix    2 * 3 + 5
             2 times 3 plus 5.

    Prefix   + * 2 3 5
    Lisp     (+ (* 2 3) 5)
             The sum of the product of 2 and 3, and 5.

    Postfix  2 3 * 5 +
             With 2 and 3, multiply. Then with 5, add.

Ahh, understood now. I figured postscript as it's also a concatinative programming language.

I read postfix as in the mail server not as a synonym of suffix, thanks for the clarification.

> synonym of suffix

Antonym, actually. Prefixes are literally on the other end of things than suffixes are ;)

He's talking about postfix, not prefix. It's closer to being a synonym of suffic.

Oh shit, true. My mistake. Sorry!
