haraka-plugin-graveyard v1.0.0

haraka-plugin-graveyard

Forward messages to another server for continued retry attempts after a configured amount of DENYSOFT values are returned.

Configuration

• config/graveyard.ini - configure max soft bounces before queued for graveyard

Example

; config/graveyard.ini
[graveyard]
max_failures_before_graveyard = 2
next_hop = 127.0.0.1:9025

Caveats

You'll want the configured max_failures_before_graveyard value to be lower than the maxTempFailures value in the outbound.ini file. Possibly much less -- if the process is restarted, then the count of failures before sending to the graveyard is reset, so a hard bounce may occur sooner than you expect in such a situation.

Really, this plugin is intended to forward a message to a server that's dedicated to retrying soft denies much longer than a machine with good standing should, so setting the maxTempFailures to 13 (the default) and then setting max_failures_before_graveyard to something like 1 or 2 would be perfectly appropriate.
