8 - Licencing

When you initially install Mailismus, the downloaded distribution does not include a licence file, so it runs in a restricted trial mode.
You are allowed to use Mailismus for a period of up to 4 weeks in this trial mode, and the restrictions are as follows:

This unlicenced trial mode will allow you to get Mailismus up and running, but we will also be happy to provide you with a full evaluation licence on request. This is free of charge, and provides the exact same functionality as the full licence, except that it expires after a few weeks.
The evaluation licence is available via the same home page as the full licence, and you configure licences into mailismus.xml as described in §4.1.

Finally, if you decide you want to keep Mailismus, you can purchase a licence by going to the home page.
This licence will remove all restrictions, and is is valid forever, without time limit. In other words, it's the evaluation licence with the expiry date stripped off.

We would strongly recommend you obtain the evaluation licence before buying one, both to verify that Mailismus will work as expected with your supplied system info, and to enable you to fully evaluate and benchmark it under conditions of high-volume traffic - which is what it excels at.

Note that the software you download is already the full software. It is just the type of licence file (or absence thereof) which determines its capabilities.
The logfiles will indicate whether a full licence was detected, or which restrictions are in force.
