for sendmail, you can do stuff like this:
# Don't throttle localhost
Connect:localhost       RELAY
GreetPause:localhost    0			# Time to wait before 220 msg
ClientRate:localhost    0			# Connections/interval
ClientConn:localhost    0			# Concurrent connections
# Default
GreetPause:             1000
ClientRate:             10
ClientConn:             10

For mimedefang, checkout filter_relay, where you can specify a
delay on return to teergrube the client (thusly stalling one
mimedefang thread - but shouldn't impact other deliveries)
