    • For incoming mail, on your server run a mail retrieval agent like fetchmail to fetch mail from the externally hosted mailbox into a maildir on your server.
    • To serve that maildir to your clients, on your server run a mail delivery agent like the IMAP server Dovecot.
    • To accept outgoing mail from your clients, on your server run something like Postfix with a relayhost configured with the details of your externally hosted SMTP server.

    There’s nothing unusual or tricky about any of this arrangement.

    The ban and age verification requirements apply to pretty much all services which allow communication of information between people, unless an exemption is granted by the minister.

    There is no legislated exemption for instant messaging, SMS, email, email lists, chat rooms, forums, blogs, voice calls, etc.

    It’s a wildly broadly applicable piece of legislation that seems ripe to be abused in the future, just like we’ve seen with anti-terror and anti-hate-symbol legislation.

    From 63C (1) of the legislation:

    For the purposes of this Act, age-restricted social media platform means:

    • a) an electronic service that satisfies the following conditions:
      • i) the sole purpose, or a significant purpose, of the service is to enable online social interaction between 2 or more end-users;
      • ii) the service allows end-users to link to, or interact with, some or all of the other end-users;
      • iii) the service allows end-users to post material on the service;
      • iv) such other conditions (if any) as are set out in the legislative rules; or
    • b) an electronic service specified in the legislative rules; but does not include a service mentioned in subsection (6).

    Here’s all the detail of what the bill is and the concerns raised in parliament.



  • Yeah nah, that’s not the way. Sure people can get away with it, but it’s really not eliminating the hazards.

    There’s a bunch of non-obvious hazards which exist around cutting into containers which have held fuels, including but not limited to:

    • An empty propane container could have an gas+air mixture inside it in proportions which could explode.
    • Any liquid residue in an empty fuel container can be vapourised by the heat of the cutting, creating a fuel+air mix which can spontaneously explode from the pressure and heat, even without sparks (think: diesel engine principle but instead of a 0.25L cylinder it’s a 200L cylinder).
    • An empty gas canister can be contaminated with heavier oils/waxes that could build up over the years of refilling cycles, creating the same hazard as noted for empty liquid fuel containers.

    Methods to reduce the hazard include:

    • Thoroughly washing the inside of the container before cutting (access can be difficult though).
    • Filling with water and cutting while full of water. (Container musn’t be sealed, and the cutting method must be safe to use in a wet environment, and further hazards such as introducing oxygen into the container need to be considered).
