The mail system

<abc@me.com>: host smtp.abc.net[67.45.256.209] said: 554 5.1.8
<info@domain.local>: Sender address rejected: Domain not found (in reply to
RCPT TO command)

(Federico Ballarini) #2

Yes because you are exit with a domain.local and if the recipient server verify the address, your address it’s invalid.

(Amort Gottfried) #3

Thanks for your help, so what am I supposed to do … Sogo sending works.

(Federico Ballarini) #4

But why are you sending with a .local domain?

(Amort Gottfried) #5

Have the server with nethserver.domain.local installed.

(Federico Ballarini) #6

Yes, but you can add a second email domain and change identity of user to exit with another domain.

(Amort Gottfried) #7

Hello, I have already done that, domaine .it. Where can I change the identity of the user for the external domain to appear?

(Federico Ballarini) #8

Please have a look to this post. I think it can be a solution.

So I should put it this way?

(Federico Ballarini) #10

You have to modify the file /etc/postfix/canonical by adding at the end of the file this line:

user@domain.local user@yourdomain.ext

Replace user and yourdomain/ispdomain with real values.
Then launch command postmap /etc/postfix/canonical and check that it doesn’t return errors.
If yes restart postfix with systemctl restart postfix

Use real name instead of domain.local and yourdomain.ext

is this correct?
