Email not working properly

Support Software & Applications

I have a problem with Email sending.
I have three computers.

The working station can´t send Emails to poststelle@bgh.bund.de.

The mail system [<poststelle@bgh.bunde.de>](mailto:poststelle@bgh.bunde.de): host bgh.bunde.de[46.243.95.178] said: 554 5.7.1 [<poststelle@bgh.bunde.de>](mailto:poststelle@bgh.bunde.de): Relay access denied (in reply to RCPT TO

Two computers are working fine.

Where do I begin to search ?

2

Email sending how? Some particular email client, command line? (what command?), something else?

What errors showing?

3

Did you check the difference:

@bgh.bund.de versus @bgh.bunde.de?

4

I am using Thunderbird in the latest stable version (115.12.1.).

On all computers, the same Email program is running.

I have checked the Email sending on all 3 computers.

On two computers, the Email sending is working.

The Email adress is poststelle@bgh.bund.de.
This is Bundesgerichtshof (= same as Supreme court in USA).

Where are the IP adresses saved in Thunderbird ?

5

There are no saved IP addresses in Thunderbird. What do you mean.

You used the wrong mail address.

6

Yes, this is the problem.

Thanks!

Over night, the pre saved Email adress was changed.
