Diagnostic-Code: smtp;550 Rule imposed mailbox access for info@delangstraat.rabobank.nl refused: user invalid
This error comes immediately when sending the e-mail to Rabobank via Thunderbird. When sending the same mail via Webmail KPN, things are going well. The problem is therefore NOT at Rabobank, but at some institution of my own Thunderbird. Is there perhaps someone who knows something more about this and could help me?

The problem is suddenly completely solved by itself. I have not changed or modyfied anything. Anyway, I am happy and thank everyone who has thought along.

I would guess that the email address you are using in Thunderbird has a blank leading space. so it is being sent as " info" not "info"
I have carefully checked the sent messages and also my address book, but my e-mail addresses do NOT start with a space.
it could be that there is no info at that domain. delangstraat does not appear to be part of other rabo bank email addresses in the Netherlands.
The same message sent via the webmail service of KPN, or via hotmail.com goes well. The e-mail address then also responds with a correct confirmation. So the problem seems to be somewhere in my own Thunderbird. I have reinstalled the program, but this did not solve the problem.
