Re: Is it just me or does this seem like a lot of effort and risk?
A good few hours effort, for sure. Depends if you think the benefits outweigh that.
In terms of risk, probably less than there used to be - with a modern MTA, I think it's a bit less likely that you'll accidentally set up an open mail relay without intending to, whereas with Sendmail and some other old software, it was very easy to do that unwittingly.
