The demos on the web for use with indy (10.5.7 in Delphi XE) are very old, there are not working not with Delphi 2007 or newer. Is there a short demo for to setup an Pop3-Mail server with Delphi 2007 or newer with Indy 10.5.7?
The demos on the indy-website are from 2004, it is sad that there are not newer demos.
AT first thanks to all the experts, who gave me an answer.
The Link from ewangoya I have found here before in the experts website, but the link goes to on old example, that does not work.
The Links from jimyx helps at the end: The demo at fulgan.com was indeed newer und with the link to the yahoo-group I have post my not working code and Remy Lebau gave the last tips, so now my problems are solved.
There is an article and source code for a pop3 (Indy 10) server in this site

Hope that helps
