I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

haraka plugin graveyard fallback relay

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.
