You could break the glass and roll back the year numbers on this comment, switch the "Exim" badge to "Sendmail", and sell this as an authentic comp.security.unix post circa 1996. I think we can see in retrospect what an absolute debacle that was for the Internet. The difference is that today we have better options. Postfix is written in C, and none of us should be comfortable with that, but it's not macraméd out of heap overflows, and its heap doesn't start with a blob that will shell-expand to system commands.
