I guess the reason is that mail documentation is mostly 
contributed, and was never seriously considered by the 
documentation project.

The smtp_client_buffer directive is identical to 
imap_client_buffer, but for the smtp module.

The smtp_greeting_delay directive allows introducing an artificial 
delay before sending an SMTP greeting, and rejecting clients who 
fail to wait for a greeting before sending commands.
