I tried to tell my provider, but to no avail. Until now I used gmail,
but gmail will disable that ability by end of this month, leaving me
in the dark. Lose-lose situation for me. Right now I don't have a
useful alternative that doesn't require me to change my e-mail
address completely (or setting up my own e-mail server which
is a pita).

Another lose-lose situation. Larry tells me I should use
be16_to_cpu(), you tell me I should not.
Either case, https://lore.kernel.org/r/YkPK/QmLAp3BkygY@sckzor-linux.localdomain
is a more complete solution, so you might want to pick that one.
