I think IDENT is in sendmail because it was supposed to be effective
against spam. It was not, and I think one major reason is that it
never reached the critical threshold.
Side note: That is not the origin of IDENT protocol. IDENT had nothing to do
with 'spam'. It is a completely different beast with a completely different
and more esoteric origin.
Besides, IDENT for mail seems very similar to RMX. How would
checking IDENT values for incoming mail differ from checking RMX bits,
other than in trivial matters like using port 53 instead of 113?
Huh? IDENT is not used for that type of purpose and should not be used to
authorize or authenticate any activity on Internet.
