relay not permitted, authentication required

[gate2vn]

As mentioned in the subject, that is the error when sending out an email. The domain is existed in /etc/virtual/domains already. With the same domain, another account can send out without any problem. Only one account cannot send out with that error message.

I also check in /etc/virtual/the-domain-name/passwd to make sure the troubled account there, and it's there.

I am using exim.conf 4.5.7

Any other place that I can check to find out the reason?

Thanks.

Might be an issue with the exim.conf file, once verify this.

 

[gate2vn]

It should not. Because if it's an issue with exim.conf, it will affect to all accounts. But even with the same domain, other accounts can send out, only one account cannot.

It would mean that an authentication fails, make sure that you use correct username/password, try to connect to roundcube to make sure your credentials are fine and try to send an email from there.

More details can be probably find in logs /var/log/exim/mainlog

When I installed that account in Mail, it can still receive emails. I even tried to reset the password and updated in Mail, the same error happens. Sending from webmail is just fine.

It's not by any chance the system account you're using? The accountname you use to login with followed by @yourdomain.com?

Actually if you receive emails it's OK, you need to make sure that SMTP auth is enabled in your mail program. Depending on your exim.conf version it might be obligatory to use SMTP auth.

I am not sure what you mean with the system account, but smtp is configured with the full email [email protected], not only accountname.

 

[Richard G]

The system account is the accountname which you use to login to Directadmin. Are you using that one?
Or did you create a seperate email address?

 

[gate2vn]

No, I am using a separate email, not the DA account.
