Out of the box Exchange Server does not support DKIM signing. And it doesn’t look like Microsoft has any intention of adding this feature any time soon. So for now the best way to implement DKIM signing is via third party a plugin.
DKIM (DomainKeys Identified Mail) is an email security standard designed to make sure messages weren’t altered in transit between the sending and recipient servers. It uses public-key cryptography to sign email with a private key as it leaves a sending server. Recipient servers can then use a public key published to a domain’s DNS to verify the source of the message, and that the body of the message hasn’t changed during transit. Once the hash made with the private key is verified with the public key by the recipient server, the message passes DKIM and is considered authentic.Source: https://postmarkapp.com/guides/DKIM
If you want to know more about how DKIM works, Postmark provides a pretty detailed explanation.
Exchange DKIM Signer is an open source, easy to install DKIM Signing Agent for Microsoft Exchange Server. It includes support for Exchange Server 2007 through to 2016.
1. Download the latest GUI package: https://github.com/Pro/dkim-exchange/releases/latest (Configuration.DkimSigner.zip)
2. Extract it somewhere on your Server (e.g. Desktop)
3. Start Configuration.DkimSigner.exe
4. Select Install
5. Once the installer has completed, click Close
1. Now configure the DKIM Signer with the installed GUI. Navigate to and launch the configuration executable (located under "C:\Program Files\Exchange DkimSigner\Configuration.DkimSigner.exe".
"C:\Program Files\Exchange DkimSigner\Configuration.DkimSigner.exe"
2. Click Configure and move the priority of the DkimSigner Agent up to at least 3, if not 1 (This is to prevent other agents from potentially interfering with the headers), and then click Close
3. Navigate to the DKIM Settings tab and change the Header & Body Canonicalization options to Relaxed. Click Save configuration to save your changes. See DKIM Canonicalization – or – why Microsoft breaks your mail for reasons why choosing Relaxed over Simple may be the better option.
4. Now switch to the Domain Settings Tab. Fill in your Domain name and Selector and click Generate new key. DKIM Signer will then generate new public and private DKIM signing keys based on your chosen domain and selector.
Generate new key
A save window will open prompting you to save the newly generated key in "C:\Program Files\Exchange DkimSigner\keys". Click Save.
"C:\Program Files\Exchange DkimSigner\keys"
You can save the generated keys to an alternative location if you wish. However DKIM Signer recommends storing them in the default location.
IMPORTANT: Make sure the user you’re signed into your exchange server as has permission to access whichever path you choose to store your keys. Otherwise you’ll encounter access denied errors: "Couldn't load private key for domain mydomain.net: Access to the path 'C:\Program Files\Exchange DkimSigner\keys\mydomain.net.pem' is denied.". And DKIM signing of outgoing mail will fail.
"Couldn't load private key for domain mydomain.net: Access to the path 'C:\Program Files\Exchange DkimSigner\keys\mydomain.net.pem' is denied."
5. Now you need to publish the DKIM TXT record for your domain (mydomain.net) with your DNS provider. Make a note of your Suggested DNS Name and click Copy to clipboard to copy the Suggested DNS Record.
Suggested DNS Name
Copy to clipboard
Suggested DNS Record
Now head to your DNS provider to create your TXT record.
6. Select TXT record as the type of record to create and for the TXT record Name, enter your Suggested DNS Name (key1_2017._domainkey).
*Most DNS providers automatically add your domain name to the end of the TXT record ‘Name’ entry, so there should be no need to enter the whole record e.g. key1_2017._domainkey.mydomain.net.
For the TXT record content, paste your copied key and save.
Wait a few minutes for the record to propagate (Most DNS providers are pretty quick these days) then head back to the DKIM Signer Domain Settings tab and click Check. DKIM Signer will query your DNS record and if all’s well your record should now be verified as correct. Click Save to save your domain settings.
7. Switch to the Information tab and restart the Exchange Transport Service by clicking on Restart.
DKIM Signer is now configured to sign emails originating from your domain.
1. Open your web browser of choice and navigate to http://dkimvalidator.com/. Make a note of the randomly generated email address. DO NOT CLOSE THE BROWSER/TAB, you’ll need to return to this page shortly.
2. Log into an Exchange mailbox associated with the domain you’ve just setup and send an email to this random address.
3. Allow a few minutes for your email to arrive at dkimvalidators.com’s site then return to your browser and click on View Results.
If you see results = pass, congratulations, your setup is complete and you can now send email verified using DKIM signing.
results = pass

Lucky 8 Proud Rhino Hidden Winch – I specifically asked for the model that had been slightly modified to fit the MY19 model. I know someone who had a tray from 2018 that struggled to fit the MY19 vehicle. Email communications with Lucky8 ensured the correct tray was sent.
This is what arrived exactly. No bolts etc. As it turns out… you don’t need any. You will see later.
Domin8r x 12,000lb Winch with synthetic rope. – Note that as of 2020 there are two two Domin8r winches available. The one pictures and the Extreme. The extreme has an improved brake system and on inspection was a little larger in height. Because of this and the fact that I had seen images of the “standard” or orange rope version installed on this exact fit, I went for the standard version.
Pictured is exactly what arrived in the box.
I did consider a Warn which, however the price is literally 10 times the cost of this kings winch. And the fact that my Discovery while used hard will never be an extreme 4×4. The winch I am fitting servers two purposes for me.
1. It lets me explore tracks and go “down” places without the anxiety of getting stuck.
2. It lets me recover myself and others more easily that perhaps I would without the winch option.
In all honestly, on my previous LR’s fitted with a winch, I only ever used it twice and both times could have used other options. But I did find the comfort of knowing it was there completely changed how willing I was to explore hard tracks alone.
So the cheaper winch, it it only works a handful of times will suite me fine!
I added the wireless which controller option to allow me to use the controller at the wheel without wires.
You can see that there is a dongle that plugs into the control box, and the remote that confusingly comes with wires, but the can be removed.
Factor 55 1.0 Grey Fairlead
1.5” 5/8 screws with Hex Heads and a couple of washers.
3M Automotive double sided tape.
This tape is used to refit the side strips around the wheel arches.
This for my was by fat the hardest part of the job. Knowing where to screw and pull to unclip and remove the bumper was not something I could do alone. So I enlisted a Landrover Mechanic (Tom) to assist me on the removal and refitting of the bumper. Super handy having him there to do it professionally. Total time to remove was about 40 minutes.
Not really going to try and describe the steps to remove the bumper. After seeing it done, I don’t think I would attempt it again without help. There is a bit to it. But some interesting steps included….
Removing the side strips around the wheel arches required carefully prying the double sided tape off, and disconnecting the sensor plugs. We used the 3M double sided tape to fix them back on.
The front radar sensor fitted the the cross bar. This is the bar that will be hacked into to make room for the winch.
Note the plastic dieting trim at the top and bottom of this image. They effectively directed air through the radiator. We managed to keep the top, but the bottom had do go.
This front scoops here are to direct air onto the brakes. We managed to refit these after the tray was added.
Removing the bottom plastic air direction housing.
With it removed.
You will notes that there is still a plastic scoop at the bottom. We cut this off wish industrial scissors that made easy work of the plastic.
This is the cut away bottom plastic air duct. Both sides shown here to assist you with how much to cut.
We decided to unplug the cooling pipes to give us more room. We saved and used again the cooling fluid.
This hose in the middle frame was one that was tricky to fit back. You can see in this image that the tray is in place, although not tight. The hose comes around the tray and would rub on the tray. We decided to fit a foam block between the hose and the lucky8 tray. Something like a pool noodle cut to size would work well here. Something that fit around the host, but between it and there tray to ensure that vibration stays away.
Now this is not a picture of my bar. And I cannot believe it that I did not take a picture of the cuts we made before fitting the winch tray and winch. But we effectively made the same cuts as were made here, but did not remove the bar from the car to do it. Simply cut with the bar fixed to the car. The cuts were not hard, and worked well with a standard angle grinder. A couple of things to note in this.
1. The bar is much more sturdy than it looks here.
2. The middle remaining square bracket is to allow fitting of the radar back in place.
3. The cut on the back o the bar on the right side, needs to be a little angled to the right. i.e making some more room on the back right bottom.
The end result with our bar. Note again the cuts in the bar. The winch in place.
You will also note that we fitted the control box with the plug sitting forward. This worked very well and allowed some of the cables to come forward of the bar, and some to go behind the bar. To fix the control box we simply straightened the mounting bracket in a vice, then drilled a couple of holes through the bracket and bar then fixed it with some metal tapper screws.
Note the alignment of the box plug just to the right in the image of the screw holes below. This allows the box to be accessed from the front through the grill once the bumper is reattached.
Winch orientation is important. Note that the direction we have the winch allows the winch rope to run in on the bottom of the winch. I have seen the winch fitted the other way around, but this means that “in” on the controller will wind the rope on the top of the drum. Note idea for winches as it puts more moment on the attaching bolts. We found that fitting the winch this orientation worked fine.
The cables were easy. Two leads gong back through the front assembly to the right are fixed to the jump points in the car. The red cable that loops back from the control box and under the cross bar, that you see on the bottom of this image is actually visible from the front of the car. So fitting a black or shrink wrap here would discuss that better.
You can see here too the radar fitted back in place and the winch cables zip tied to the top of the cross bar to keep excess cables from rubbing around the place. It is also interesting that the zip ties are visible from the front, so we used black to make it cleaner from the front view.
The mounting brackets took a bit of playing around with to get them orientated correctly. When we did, it all fit well and was obvious. This pic shows the orientation dangling down. We swing them into place 180 deg and use the winch bolts to fit them up through the tray and into the winch.
You can see here that the bolts going up through the tray are the Domin8tor winch bolts that came with the winch. They go up through the winch brackets and tray and into the winch mounting lugs.
The direction of the brackets works well in this orientation. We tried to have the brackets the other way around to put the bracket angel mount outwards for better strength. However we found they would not fit in that orientation. But we are happy with the result here.
The cables that come up behind the light assembly.
Then run up over the air box
And fitted beneath the jumper mounts.
We did consider fitting them to the winch mount (that comes on the discovery) that is behind the front right wheel guard, and it would have worked. But the problem is that the Domin8tor winch has the in lead fuse that you can see in this image. There would be no way of easy access to that fuse if fitted to the winch mount. So we elected to fit it here. With zip ties it is very sturdy and works well.
This picture shows the winch cables zip tied in place, but also the car cabling tied back over the top of our work.
The end result before the bumper was attached again.
With the bumper fitted and the winch rope just temporarily zip tied out the way.
To get the factor 55 1.0 fair lead to fit, we need to make two cuts to the bumper just either side of the fairlead. The cuts are to the vertical plastic moulding. We made the cuts at the bottom and just screwed the factor 55 fairlead inlace while holding the plastic open using a bit of bruit strength.
The result is that the bumper splits a little wider around the fairlead and is a little deformed from its original shape. But the end result is that the fairlead sticks out a little giving good clearance for the rope to stay away from the bumper, and the whole thing looks good from the front. We made the cuts with a multi tool in about 5 seconds. Easy work.
Not the control box is still accessible from the front, but mostly hidden. The wireless dongle sits really nicely in place and could be left there for a day out with a bit of winch work anticipated.

Tom – The Landrover guru who helped with the bumper and whole job
Darub Abrahams – Who shared his experience with the older tray and some of the notes that helped with my decision making.
This is a Landrover Manual extract that talks about their winch fitting option that they never released. I referenced this a bit, but this blog post would be more help to anyone doing the same thing.
If you live in Sydney and want a Landrover mechanic to assist you with this winch combination, then please contact me. Tom would be only too happy to help.

Once the SSL certificate is installed, your site still remains accessible via a regular insecure HTTP connection. To connect securely, visitors must specify the https:// prefix manually when entering your site’s address in their browsers.
In order to force a secure connection on your website, it is necessary to set up a certain HTTP/HTTPS redirection rule. This way, anyone who enters your site using a link like “yourdomain.com” will be redirected to “https://yourdomain.com” or “https://www.yourdomain.com” (depending on your choice) making the traffic encrypted between the server and the client side.
Below are steps to setup a IIS HTTPS redirect:
The IIS redirect can be checked by accessing your site via http:// specified in the URL. To make sure that your browser displays not the cached version of your site, you can use anonymous mode of the browser.
The rule is created in IIS, but the site is still not redirected to https://
Normally, the redirection rule gets written into the web.config file located in the document root directory of your website. If the redirection does not work for some reason, make sure that web.config exists and check if it contains the appropriate rule.
To do this, follow these steps:
