I found some discussion about the similar greet_pause setting in
sendmail that indicated that at somewhere slightly below 30
seconds you'll start to drop some legitimate mailers. Some
places mentioned needing to whitelist a few sites but it seemed
to be caused by misconfiguration on the other end rather than
a specific mailer type that doesn't wait. It also sounded useful
to be able to avoid the delay for your local networks which
sendmail handles with entries in the access db.
It would be kind of nice to be able to combine the need for
this check with one for greylisting in a local database.If
a given sending IP address has passed the tests once there's not
much sense in imposing any delay again for a while.
