Email Greylisting

Posted on November 27, 2010 by Null

First, for the un-initiated, click here to learn about email greylisting.

When email admins talk about greylisting, one of the benefits they normally point to is load on the actual email server but fail to mention supporting systems. I did notice a decrease in mail processing load there as well as my database server.

Keep in mind this is NOT a busy email server. It’s only hosting a couple TLDs.

I noticed an immediate improvement after restarting mail services (I did not reboot the server).

Delayed Site Loads

Posted on November 25, 2010 by Null

Recently all the sites hosted on the WordPress platform were experiencing delayed loads.

I was able to trace this back to the plugin Wordbooker, specifically version 1.8.17.
All sites have been upgraded to version 1.8.18 which seems to alleviate the issue.
