Lawful Intercept: IMAP (imap-intercept) Plugin

Note

This plugin is provided by Dovecot Pro's Lawful Intercept Framework.

Intercept IMAP session traffic.

Configuration

protocol imap {
  mail_plugins = $mail_plugins imap_intercept
}

plugin {
  #imap_intercept_disconnect_after = 12h
}

The interception is enabled if userdb returns a non-empty intercept extra field.

Plugin Settings

imap_intercept_disconnect_after

Default	[None]
Value	time

The IMAP client is disconnected after this amount of time, and interception is discontinued.

This timeout prevents repeated interception of a very long session (disconnection is performed for all users, so that interception-specific behavior isn't obvious to the user).

intercept_debug

Default	[None]
Value	boolean

Normally, the intercept plugins don't log much of anything, even in error situations, because we want to avoid making visible which users are being intercepted.

Set this value to true to output additional debugging information.
