I've missed the memo saying that I should change it, if I run the
gateway in Linux. :) I mean, that's why I'm asking. I'm missing a
relevant section in a RFC stating that a global relay should be
configured according to XYZ, due to ABC. Even after reading tens of RFCs
multiple times, it can be hard to distill that XYZ.
