Halon has been chosen to participate in the growth acceleration program Scale Global. During the period of September 2017 to January 2018, Halon and seven other companies will get help with the transition from nailing the product to scaling their business. The program rests on three pillars; workshops, coaches and Silicon Valley.
The companies will be working together on a number of workshops, one of them being a one-week stay in Silicon Valley, having meetings with partners at AndreessenHorowitz and True Ventures, Gustaf Alströmer (partner at Y Combinator), Cindy Alvarez from Microsoft and Maxime Prades of Algolia, to mention a few.
Time-of-click protection adds an extra layer of security to protect email users from accessing malicious content. Attacks including malware, ransomware and phishing are becoming more common and more sophisticated with every day, along with users keeping more sensitive information.
With an additional time-of-click protection, Halon will classify links in email every time it’s clicked, before allowing or denying the user to visit it. This means that if the scammer waits two minutes or two months with infecting the site, the user will still be protected when he or she chooses to click the link. It’s the extra layer of security that won’t allow you to visit infected websites by way of a link in an email protected by Halon.

We have done two new releases of Halon since last time we updated the blog with release matters. In Halon 4.1 “teamy”, released just before this summer, we introduced modules. A month later we followed up with 4.2 “classy” that added proper object orientation to the language (which works great in combination with modules). It spawned a few rewrites of our script examples (modules) to reflect this awesomeness. We initially added instance and class methods and variables (static), and in 4.3 “cody” we added the private keyword to functions and variables as well.
private $name = "Dr Who?";
$this->name = $name;
return "Hello ".$this->name";
static function ...()
We’ve created a lot of modules and script examples. Some of those, such as the PostgreSQL and MongoDB modules, rely heavily on byte packed data structures. In order to better support those, we’ve added built-in functions such as pack() and unpack(). Upcoming modules and rewrites will also benefit from the new TLSSocket() class.
Here are some new additions to our module collection:
Other notable features from the changelog includes
FreeBSD 11.1 and new quarterly packages
sha2 hash functions
Added status and NDR codes to Reject, Defer and Deliver functions
SetTLS support CA name verification
DLP engine now support file hashes of SHA2-256 and SHA2-512
Added $sourceip variable to post-delivery script to easily determine which IP address that was used to send the mail
Geek out corner
One major change that only we can see and fully appreciate is the (both automated and manual) code migration to C++11 (and forward), using the truly awesome clang-tidy tool.
On another note; while we researched pack and unpack implementations by looking at other languages’ documentation (such as PHP, Perl and Python), we found a bug in PHP, which was fixed in 7.2, and backported to 7.1.9. The overall consensus of syntax and conventions amongst languages regarding how pack and unpack should work seems to reflect and mimic Perl.
“In a language with an automatic garbage collection mechanism, it would be difficult to deterministically ensure the invocation of a destructor, and hence these languages are generally considered unsuitable for RAII [Resource Acquisition Is Initialization]” – Wikipedia on destructors
MongoDB does unlike many other databases use little endian and not big endian (network byte order) in its wire protocol. This will let you send and receive data structures in native machine endian (for most people) since both x86 and amd64 use this convention. I highly recommend reading up on the fun historic trivia about endianness.

Ensuring high deliverability in email is no walk in the park. As a high-volume sender of email, there are many things to take in consideration, especially with cybercriminals keeping a fast pace in innovation.
Make no mistake, deliverability is of highest importance to anyone sending email, let alone the high volume senders. When you get the information from your servers that a certain percent of sent emails were accepted by the receiving servers you still have no idea what happened after that. No confirmation of emails actually reaching inbox means they might just as well be laying in the spam folder. The SMTP transaction is logged as ”250 OK” as long as the server didn’t reject the email. To make matters even worse, different ISP’s may treat email differently, putting more responsibility on the sender to do their homework as neat as possible.
Pay attention to encryption, as it no longer is as security measure only for the selected few, but becoming the standard. TLS/SSL and DANE are your friends and will keep your information private.
Be protective of your IP addresses reputation, they can make or break your deliverability. ISP’s acts as proxies for recipients, meaning they will take reputation very seriously. Take in consideration that sending unsolicited email may harm your IP reputation, and authenticating your email with SPF, DKIM, and DMARC will help keep out scammers who are most often ahead of ISP’s and senders technology.
Telecommunications company KPN, the largest provider of internet access services in the Netherlands, has agreed on implementing Halons email infrastructure and security software.
”As the largest ISP in the Netherlands, we believe in connecting people and enabling them to communicate with the world around. Because of that we provide full functional, secure email as a part of our portfolio. But a constantly changing internet environment and attacks becoming more and more sophisticated, managing such an email platform can become quite a hassle. We are always looking for improvements in functionality, flexibility and performance” says Martijn Thie, architect at KPN.
”In Halon we have found a great partner for that. They are not just delivering their software, but they’re really keen on working together and learning from our situation. Even before we could enable Halon for our email products, additional functionality was added to make it an even better fit with our environment. Halon SMTP is the most flexible, sophisticated and easy-to-manage SMTP server out there.” adds Martijn Thie.
”We are proud and glad to welcome KPN as a Halon customer, and help them secure their users email. With the Halon taking care of email infrastructure and security KPN can now improve the performance of their email platform” says Peter Falck, CEO and co-founder of Halon.
To email hosting and service providers in or around Switzerland, we kindly invite you to join an intimate group of Cloud and Telco VIPs for an exclusive Email Security Roundtable to introduce you to the Trusted Email Services (TES) initiative. Date: Thursday, September 21, 2017, hosted by Open-Xchange.
TES was launched as an industry e ort to raise awareness around email security threats and promote the deployment of innovative technologies to address them, including encryption and DNS-based mechanisms such as DNSSEC, DANE and DNS filtering. The discussion will deliver an insight into how internet service providers and software companies adopting TES guidelines and best practices can secure and qualify their services, comply with recent legal requirements (GDPR) and establish enduring customer relationships.
