Early talkers are violators of the SMTP specification, which require that clients must wait for certain responses before sending the next command.

This plugin introduces a configurable delay before the connection banner and after the DATA command for Haraka to detect if it talks early.

If an early talker is detected at connection or DATA, then a DENY is returned with the message 'You talk too soon'.

The config file early_talker.ini has two options:

• pause: the delay in seconds before each SMTP command. Default is no pause.

• reject: whether or not to reject for early talkers. Default is true;

• [ip_whitelist]: list of IP addresses and/or subnets to whitelist
