comment mx server: multiple domains on one ip
@sebix I did specify hard fail (-all) which I use everywhere. I did grab the wrong SPF specification from my web server, instead of the the correct one from my mail server. I've updated using the A record rather than the MX record as there is no MX for the mail server. The domain should use MX but I didn't include it, but have now.

comment hdparm serial number is garbage
The emulation of cylinders, heads, sectors, etc. is essential to being able to use the device as modeled by software. The serial number and many of the other items reported by hdparm are related to the physical implementation of the device. (Serial number is not even required at that level.) Many are related to the hardware controller software not the device itself.

comment hdparm serial number is garbage
Virtual machines generally have virtual devices. Using a tool intended for physical devices is likely to get invalid results.

comment Exim4 on DebianWheezy: Rejected by RCPT Unrouteable address
@Jukodan You should need no changes to the template. Just add an entry to /etc/exim4/hubbed_hosts. This file may not exist yet, so you would need to created it.

@Jukodan I've added details to my response. The hubbed_hosts file should be able do the routing for you.

comment Hacked server or someone is email spoofing
@Power-Mosfet Unfortunately, in my experience, the larger the organization the more likely they are open to basic abuses. Organizations like banks, governments, airlines, couriers and the like rarely have SPF records.

comment GMail bouncing mail sent over IPv6, IPv4 working
@JohannesH. IPv6 has a mechanism to generate the last 64 bits of the address using the MAC address. This results in addresses with lots of bits set. When addresses are manually assigned they usually two or three address sections are 0 and can be replaced by ::. You could use something like 2a02:748:a800:ca7::25. Users using privacy extensions would also have address sections with no zeros, but the addresses change periodically.
