The Web Developers Conference is aimed at both professionals and students, and focuses on the front end side of web development.

The schedule has now been released, and the speakers have been known for a while, there are a couple of well-known speakers that will be there so I’m really looking forward to this and hopefully learning a few things front end related , as a PHP developer that’s where my skills aren’t so strong.

Tickets are still available at a very reasonable £50 for the days festivities, and will be entering a Late Bird stage at the start of October, so get your tickets now to avoid disappointment if they sell out or go past your budget! Various discount codes are floating around on Twitter if you need one, or just ask one of the speakers if you’re struggling.

On the reseller server I had access to grey-listing and SpamAssassin to filter mail as it arrived and I got maybe 2 or 3 a week, but the day after I moved onto the vps this shot up to between 20 and 50 a day!  I have my emails pushed straight to my phone as well so this fast became a bit of a pain.

My VPS did come with SpamAssassin pre-installed as part of Plesk but due to the licence I have installed I couldn’t use it so this caused two problems, 1) emails are not filtered for spam and 2) SpamAssassin is using up precious memory while not actually helping.

The first thing I did was to turn off SpamAssassin, it was using a lot of memory as even tho it wasn’t filtering any mail  it was still scanning every message that arrived on the server, On advice of my hosting providers tech support I decided not to un-install it in case it caused problems so I just stopped the service from running and then disabled it from auto starting on system reboot to preventing it restarting if I ever need to reboot the server.

I then tried to find the grey-listing software used on my old reseller server, this seemed to work really well so I wanted it on my server too. Support told me they were using a script put together by Brent Meisher written to work specifically with Plesk but  unfortunately the repo had been removed and I couldn’t download the files.

I was speaking with a support engineer about it and he mentioned a new tool he was playing with called SpamDyke and how it was looking promising as a replacement to their current grey-listing solution, so I decided to give it a try.

The good news is, that since I started writing this blog post, SpamDyke has been added into the atomic repositories, so to install it is as simple as using apt get or yum. Configuration is just as simple, the default settings are actually quite effective and I’ve been using them for two weeks and haven’t received a single piece of spam.

All the information you need can be found on the SpamDyke website and the README file is really useful.
This is something I defiantly recommend to everyone who is running their own mail server.
