Gummy Bears, Yo-Yos, and Theme Parks | WHD.Global Recap

What do you get when you pair a remote area of Germany, thousands of techies, and a random amusement park? Well, you end up with what happens to be one of the most important and needless to say interesting conferences the web hosting industry has to offer.


This past week the cPanel team headed across the Atlantic to Rust, Germany and spent some quality time with our friends, partners, and customers at WorldHostingDays Global (WHD.Global).


While any opportunity to speak with our clients and partners excites us, this time we were especially thrilled. After months of toiling away, the new cPanel branding made its debut at WHD. Our new website, logo, colors, and fonts were on full display at our booth along with the newest cPanel messaging. But don’t let our spiffy business threads fool you, guests to our booth were also greeted with gummy bears, yo-yos, and cheerful conversation.

As with any conference, there was plenty of learning and knowledge sharing that went on as well. Not only did we explain the future of cPanel & WHM in our product roadmap, but our marketing whiz, Stephen Brent May, gave an exciting presentation on transferring agile practices to the world of marketing.


In the after hours, we allowed guests to come and hang out in our special lounge at the Colloseo Hotel Bar. It was here that we were able to unwind from our long days on the conference floor and catch up with our old and new pals in the hosting sphere.

Tomcat support in CentOS 7

Tomcat has had a great run with cPanel & WHM. Unfortunately, there are times in life when you know it’s time to say goodbye and gracefully remove yourself from the spotlight to allow others to get the chance to shine.

As you may know, cPanel will provide its first release of CentOS 7 support starting with cPanel & WHM version 11.50. For a variety of reasons, we will not be supporting Tomcat in CentOS 7.

The Tomcat version that cPanel currently supports is out of date and not supported by CentOS 7. Updating Tomcat to a newer version requires many dependency changes that cannot be fulfilled by the OS directly. Less than 0.1% of our user base uses Tomcat, and we feel that the amount of effort that it would take to get Tomcat running on CentOS 7 is better spent on EasyApache 4 and future expansion.

Our upcoming EasyApache release will ensure that Tomcat is no longer be available in either the EasyApache interface or the command line tools for servers running CentOS 7 or higher.

While it’s possible that Tomcat support will come back eventually, at this time our focus is shifting to EasyApache 4 and making the web stack expandable and customizable.

cPanel vs Spam: Greylisting enters the fight!

Screen Shot 2015-03-16 at 11.08.45 AMcPanel is excited to announce that 11.50 will include a new feature that  dramatically reduces the amount of spam you and your customers receive: Greylisting.

Greylisting is the process of deferring emails from unknown senders. When the email arrives, Greylisting causes the server to return a message that boils down to, “I’m busy at the moment, try again in a bit.” Valid Mail Transfer Agents (MTAs), like Exim, will automatically retry many times. This retry time can be several minutes to start and last for several days. Invalid MTAs will simply give up and move to the next enticing spam target. We use these retry attempts as a way to weed out good email from bad.

cPanel created its own Greylisting daemon, cpgrey, that runs at SMTP receipt time. This means it happens before any real data is sent. The cpgrey daemon looks for a triplet: a source IP address, a source email address, and a destination IP address. If this combination has not been seen in a set time frame (this time frame is configurable), cpgrey will defer all email from that triplet for a set initial block time (again this time frame is configurable.) After the initial block time has expired, the system will accept email from the triplet until the max block time has expired.

Greylisting has its own interface in WHM that allows root users to configure many aspects of the system. You can set the time for the initial block, the must retry time, and the triplet expire time. You can also allow emails with valid SPF records to bypass Greylisting completely. The interface also includes a Trusted Hosts page that allows you to configure IP addresses and CIDR ranges to bypass Greylisting. Finally, we have added a simple report that allows you to see the current triplets in the Greylisting database. You can even add IP addresses and CIDR ranges directly from the report.

cPanel users are able to control which of their domains use Greylisting through the Greylisting interface in both PaperLantern and x3. cPanel users will see a list of domains they control and a simple toggle to disable or enable Greylisting. Bulk actions to enable all or disable all are included in a gear icon located in the top right corner.
We highly recommend server administrators use Greylisting as a strong tool in their arsenal for combating spam.
