Stopping Exchange 2016 Same Domain Spam Spoofing

We recently converted over to using Exchange 2016 for our internal email hosting and we were immediately buried in spam. Initially we enabled the exchange built-in spam protection and it just wasn’t cutting it. We expanded out and got ourselves BitDefender Exchange Protection which promptly dropped our spam rate almost overnight. However, we were still getting emails from our own domain @infinitewebdesign.com. The best places we found to combat this involved removing the permission: ms-exch-smtp-accept-authoritative-domain-sender in the active directory for the receive connectors. This, thankfully, allowed BitDefender to at least classify them as spam, but we were still able to be spoofed. A simple telnet to our server like so: >telnet <server_ip_here> 25 >EHLO >MAIL FROM: test@<domain_here> >RCPT TO: someone@<domain_here> […]

A Quick Note on XMLSearch.

For a long time, we have considered the use of XMLSearch slow compared to working through an xml object as a standard ColdFusion structure. However, recently we have discovered that XMLSearch is actually comparable in speed to the structured approach and it was just our way of using it that was causing the slowdowns. It turns out that that we were using the “//” XPath operator at the beginning of our calls to XMLSearch regardless of where the XMLDoc object that we were supplying was pointing to.  This would cause the search function to go to the root of the document and search the whole tree.   Removing the “//” operator from the XPath portion of the call forces ColdFusion […]

Gulp Watch After Windows Restart

Recently we’ve switched over to using gulp and node.js for a few pieces of our projects and I had pondered a way to get our gulp watch process running on startup. When we reboot our windows based servers I wanted to spawn a command prompt window running Gulp Watch (or just Gulp) in our working directory so when we deploy our source there it will automatically version/build out our compiled code. I ended up using a simple Shortcut to accomplish this The shortcut should point to C:\Windows\system32\cmd.exe With the addition of /k gulp watch So Target C:\Windows\System32\cmd.exe /k gulp watch Then in the starting directory I put our working directory. Double clicking the icon launches gulp watch, I then added […]

Thankful

Today started out like many others at Infinite Web Design. Get into the office and ask how everyone is doing on the myriad of tasks they have in progress, jump on slack and check in with Kyle who is working remotely in Traverse City and then double check my email to make sure all the websites we manage are in good working order. After putting out all the fires and grabbing a cup of coffee Kevin and I hit the road. We had interviews lined up back to back all day to recruit new interns and full time developers. We were fortunate to have Dr. Issa at GEE who was willing to lend us his conference room at their headquarters […]

A Good Router

I recently upgraded my home router from the one my ISP provided to the NETGEAR AC1750 Smart Wi-Fi Router, 802.11ac Dual Band Gigabit (affiliate link)  – which is a bit of a mouthful, but also a fantastic router right out of the box. Before I bought this our devices constantly lost their connection to the wi-fi router, requiring restarting the wi-fi on the device and also restarting the router regularly. Even doing that we were often lucky to get 1.5 Mbps or any connection at all. Turns out that router stunk. As soon as I hooked this up I was seeing the actual advertised speeds from my ISP and could easily connect and use multiple computers, phones, and tablets for […]

A Good Shave

I thought I’d try something new here. I’ve found the it’s very helpful when reading other blogs when people mention products and other things that they personally use and enjoy. So I thought I’d share some of those things here as they come up. Today I’d like to mention the Braun Series 7 790cc-4 Electric Foil Shaver (affiliate link). I just bought this after 2 of the 3 cutting heads on my 10 year old Norelco stopped working. And this thing is amazing. Apparently the slow, awful decline of my old razor had reached a point where I regarded razor burn and ripping rather than cutting hairs as normal. Apparently you can actually get a nice, smooth, pain free shave […]

Peer Review

We use Peer Reviews during coding for a variety of reasons. The three main reasons are: Quality Assurance – checking other developers work to make sure everything is done correctly and works as it should. Cross Training – the reviewers going over what was done ensures that at least two people have a good understanding of everything that is built and changed. By rotating reviewers for different tasks in the same part of a system many people will be looking at what is built as it is happening. Education – the developers and peer reviewers learn from each other during the review process – new tricks or techniques are shared and developed. Peer Review Checklist We use a detailed checklist […]

Stagnation

It is hard to avoid stagnation. It requires pushing yourself and the people around you out of your comfort zone. As you get better at what you do it actually becomes even harder – you know the “right” way to do things and become even more set in your ways. So how do we keep growing ? The Comfort Zone When we start learning something new we don’t have much of a comfort zone. I’ve been teaching my son to play basketball and I’ve been realizing that simple things like not pushing your knees together when you jump are not yet simple to him. It’s a good reminder not to take things that seem obvious to me for granted. I […]

Growth

We continue growing and looking to grow our team. We’ve been very fortunate with the people we’ve hired and have been so busy we haven’t really taken the time to introduce them or explain to people why they should join us in a while. We’re now up to 7 people here. Me (Kevin), Brad, Barrett, Kyle, Brian, Tom, and Eric. A diverse group with a variety of beards. People without facial hair are also welcome, though we made Kyle work from Traverse City when he refused to grow a mustache.   [your head here] We’re working out of our offices in Lake Orion and working on plans for a new building. Brian is fixing up the Ms. Pacman I bought […]
