I can’t send emails to domains other than the main one (gmail, hotmail, etc.) from thunderbird, I can only do it to the main domain, and the error “Relay Access Denied” appears, I don’t want to touch any of the configuration without your help, once I damaged the entire mail server and I don’t want it to happen again.
Thanks
Whats email client are you using and are you using authentication.
Virtualmin should show the correct settings that you should be using.
Yes, I am using the configuration you mentioned in Thunderbird, I must clarify that I cannot do it only from Thunderbird, because I can do it from Roundcube on the web.
Relay Access Denied doesn’t make sense if you have authenticated corrected.
Maybe show the full log failure on the server, just the lines when you hit send in Thunderbird.
I just created a new email and it has the same error, I send the mailog lines with the event of sending an email from thunderbird to other domains (gmail, outlook, etc.)

I have other VPS that do allow me to send external emails from Thunderbird.
Seems like a bad username or password?
I don’t understand! Why is it called for another user and not for prueba2@consulproy.com?
Is there a problem with the configuration?
I guess because you showed us the wrong log entries? We need to see the ones for the account that your trying to use to send mail in your mail client.
Excuse me, what would be the script to get all the logs from the email prueba2@consulproy.com I’m using for testing?
You can search the log in Webmin’s System Logs modules. Or, you can search text files with grep on the command line. Or you can search the journal (if Postfix is logging to the journal) using journalctl and grep or you can tail the journal with journalctl -fu postfix. I strongly recommend you get comfortable digging into logs (and the journal) on your system. Nothing can ever be solved without being able to search/read/understand the logs.
I usually tail whatever log I am interested in, and then do the thing that I want to troubleshoot, so that I get exactly the log entries I need for troubleshooting the problem.
Hello, a happy 2025, I used journalctl -fu postfix, and tried to send an email to another domain, and I got this message.

I am sending an email to sochmal@gmail.com from prueba2@consulproy.com
It sounds like you are trying to send out directly on port 25. Thunderbird auto discovery ‘should’ have set all this up correctly.
Try port 587 and see if that works. I think 465 requires TLS through out so normal password may not work. Not sure about that one.
EDIT. Did you have VM set up autodiscovery? Have you tried letting Thunderbird auto set this stuff? Works great for me.
465 or 587 should work with authentication in a default configuration. The submission port (587) is generally the one most mail clients would use. It allows negotiated TLS with STARTTLS.
But, it does look like you’re trying to send without authentication, unless there are log entries you haven’t shown. You can’t relay to outside domains without authentication.
I have modified the SMTP port to 587 but I get an error connecting to the SMTP server. I have already modified the automatic email configuration so that Thunderbird reads, but it does not send.
“an error” is not useful information. What is the actual error? Does the connection appear in the mail log when you try to connect to port 587?
The following error appears in the Thunderbird dialog box:
Message sending failed.
The message could not be sent because the connection to the outgoing server (SMTP) mail.consulproy.com failed. The server may be unavailable or is refusing SMTP connections. Please check that your outgoing server (SMTP) settings are correct and try again.
Change the server address from mail.xxx on port 587 to smtp.xxx on port 465, show this:
Relay access denied.

Have you changed Postfix configuration WRT to authentication? This continues to look like it’s not authenticating. Not that you’ve provided incorrect auth information, just that it’s simply not authenticating at all.
So, what do you have in /etc/postfix/master.cf?
Have you made any other changes to the Postfix configuration (anything in main.cf)?
I have not made any changes to any files.
