A technical blog about HCL Connections, HCL Domino and other stuff
IBM WebSphere 8.5.5 Ficpack 27 introduced a security feature: TLS certificate hostname verification. This might provide problems in your HCL Connections WebSphere environment and will cause problems if you’re using the HCL Connections component pack if you don’t take the proper measures.

Either for HCL Connections, but also as a reverse proxy for other services. Most of those customers use a wildcard certificate for their IHS server that has to be renewed each year. As I hate this kind of repetitive work, I created a script to do it for me. As it could be of use to others, I decided to create a blog article about it.

Continue readingLast July, I presented a session for OpenNTF titled “How to use Domino as a Mail Server in a Modern World”. It was an in-depth session on the history of the SMTP protocol, new email security protocols and how to configure them to have the best chance that a mail from your domain will reach the intended recipient. In this article, I’ll cover some of the interesting things that I encountered during my research for this session and some more information on things that I covered and things that I didn’t cover.
Continue readingDomino REST API is one of the add-ons that you can select when creating a Domino container image. That creates a Domino image that includes everything you need to run the Domino REST API on your server, except when that server already existed before you added the REST API…
