550 authentication required in system mail

[santovito]

Hi to all,

I have a problem with the system email addresses ([email protected]): the emails come back with this error: 550 authentication required.

No problem with "normal" email address

Any ideas to fix?

new installation. Latest version of directadmin (and exim) and centos 8

Tnx

Vito

With system email addresses, you just use the username without the domain since the user is an actual Linux user (and not just email virtual account).
