Small data point for folk who are interested in this issue.
DKIM primarily comes from DomainKeys, which was developed at Yahoo!, by
Mark Delaney. The signature work is essentially the same.
As part of his to get Yahoo! approval to operate DKIM, Mark obviously
had to provide an assessment of the hardware and operational costs.
This was early 2000s. Even then, Yahoo!'s server farm(s) were pretty large.
His assessment was they they would need ONE (1) extra machine. Total.
Even with the horrible costs of public key encryption.
He was wrong. They turned out not to need /any/ new machines. Because
email tends to be i/o intense, leaving a fair amount of cpu sitting
around waiting to computer crypto.
That was nearly 20 years ago. Machines have not gotten less powerful.
