This message and the following discussion has deeply saddened me.
What the spammer didn't manage to do in 30 years, the antispammers
were successful: E-Mail has become an unreliable service, not because
of spam, but because of antispam.
I figured that the hard way (sending otp to new users by email): mostly work,
but failures are difficult to explain to new users.
The only "safe" way would be to communicate that kind of info through sms,
but it's very expensive.
