what I mean are emails direct on the web site. Normaly you can copy the address from the site - but this tool protect the address and convert these emails in f.e. pictures. You can've look on our site via https://fliegen-itzehoe.de/fluglehrer/  

yes - I've found a solution. 😉

You could define sites without an auto protection and than it works!

Thank you for your help and the tip of my plugin. Wish you and your team a Merry Christmas.
