"Return Receipt" comes back, normal eMails can be send.
I can send eMails with the new GMX SSL IMAP/SMTP Server and receive them. But when one of the senders asks for a "Return Receipt" I see the question if I want to send. I klick YES and see ... OK send. But then I see a bounce back error because the GMX mailserver ist blocked ... this is a OLD server, not the same that I have in my SMTP configuration . ???

I forgott, it works with the GMX WEB frontend. And it worked years ago with my thunderbird too, but now the thunderbird have this problem.
clearly those requesting the reply are blocking GMX. that is their choice.
check in Tools menu (alt+T) > account settings > outgoing server (SMTP) and change the GMX from your default to whatever you thought you were using.
