MXRoute is about a decade old and based in Texas. It’s in that “unix philosophy” category of doing something well and stopping there so you won’t get them advertising their new crypto wallet or AI software on you. It’s mostly geared for more technical bring your own domain type of usage. If you’re wanting to use it more as a forwarder and want to store the history locally (or if you don’t email files) there’s a “lifetime” plan available.
