My domain is hosted at mailbox. org. Therfore I need to use my mailadress "me@mydomain.com" and additionally I have to enter the IMAP server manually for mailbox. org. Using my mailadress shows errors and it seems that Delta Chat cuts the login name after the “@” and only sends “me” to the server. My first question is: Is my understanding of this behaviour correct?  
If yes, how can I instruct Delta Chat to use the whole name for signing in?

Kind regards  
Torsten

Was it your login/main address for [mailbox.org](http://mailbox.org)?
