<info@domain.local>: Sender address rejected: Domain not found (in reply to
RCPT TO command)

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

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

#4

But why are you sending with a .local domain?

#5

Have the server with nethserver.domain.local installed.

#6

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

#7

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

#8

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

So I should put it this way?

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

Best ist if you make a file in custom template, 70_canonical
mkdir -p /etc/e-smith/templates-custom/etc/postfix/generic
nano /etc/e-smith/templates-custom/etc/postfix/generic/70_canonical
in that file put only
@domain.local @domain.com

It works
than
expand-template /etc/postfix/canonical
than
signal-event nethserver-mail-server-update

And it works

But if i want to send a mail to an external E-Mail address with the same domain , that is not configuried in Nethserver7, than i have a problem, and not working, maybe somebody have a tip?
