Scattered throughout this website are examples of customizing Kerio Connect. You can review them using this link. Sometimes these are simple things that can be done using capabilites of the server itself and other times they require external programming. I provide Perl code for those latter examples, but the code is usually just a framework and will usually lack the features and capabilities that would be needed for deploymemt.
We can and do provide more robust code for your specific needs. You can find my phone and email at my contact page.
