You must read this page before you supply configs. By submitting configs, you place your contributions in the public domain (insofar as copyright can apply to collections of facts).

The Mail Server List is a database of email providers and the correct configuration for their mail servers. It is designed to enable services which make autoconfiguration of email clients as easy as giving name, email address and password.
Please test config information before submitting it, if at all possible (although untested data is better than no data). You are probably in the best position to try this, as other project participants won't have accounts with this ISP.
