yeah, I know that it is the spoofers who are doing the most damage to our email health, but they are a big number... they'll register a domain a day, publish an SPF record, and tomorrow, do it all over again....

No, the actual damage is being inflicted by those who spoof others' e-mail addresses with malicious intent (spammers, malware, etc.). However, innocent bystanders insisting that all this legacy "functionality" of SMTP be retained forever is now causing those innocent bystanders to become part of the problem.

If you use -all, there are situations in which your mail will be thrown
away. If you reject for failure, there are situations in which you will
be throwing away genuine mail, forwarded through normal, SMTP-compatible
systems.

Right. However the magnitude of this (1) isn't a significant problem for many people and (2) is outweighed by the benefit (no more misdirected bounces, etc.) almost all the time.

This will have been my last comment on this topic for at least another half a year. This horse has been beaten to death too many times already. *sigh*
