Bug#1053197: Configure Exim to use remote smtp without authentication

[Shaheena Kazi]

Package: exim4-daemon-light

I have a Debian 11 server with exim4 on it. I have configured exim4 to
always use Amazon's smtp server ("mail.mydomainname.com") for email
delivery.

I do have access credentials, but I want to know if its possible to force
exim to not authenticate the Amazon server credentials.

I get the below error as I have not added the creds in the passwd.client
file.

  ** root at mydomainname.com R=smarthost T=remote_smtp_smarthost
H=********************************************************************************************************************************************************************************":
SMTP error from remote mail server after MAIL FROM:<>: 530 Authentication
required

Is there any directive that can be added in the remote_smtp_smarthost to
bypass the authentication ?

 Regards,
Shaheena K
