Question
The number of messages that can be multiple deleted at once is NOT limited to a certain number of messages.
The limiting factor is the size of the GET request sent from the client to the server, handled by the web browser. When you multiple delete, the UDIL of each message is sent as part of the request. If the total byte size exceeds
approximately 2K (2048) bytes, a popup warning will be generated by the web browser.
If you have a decent level of logging enabled for the Gordano WWW service, you will see something similar to following example. Notice the total byte size reported at the end of the log. In this instance we can see the request is clearly under 2048 bytes so the request is carried out without error.

Answer
2048 bytes is the advised configuration. Should you wish to increase this limit you can but you do so at your own risk.
To increase the default value, browse to the "System Variables" section of the admin interface.
Add a new value of MaximumURLLength and enter a value in bytes. This variable can also be set at a domain and user level.
