Thank you for your response but I’m sure the email is already out, please see the photo

That just indicates that the webmail client (Roundcube) has copied the message to the “Sent” folder of Roundcube. That is not the same as it actually leaving the server’s queue. Try sending a test mail using the Usermin for the user.

Virtualmin -> Edit Users then select the user then the button “Login to Usermin” create your test message then send it.

I think it’s the same problem thank you for seeing the photo I see that the emails are already on the send box parked like they are already sent but on the person box which one it is it is addressed to I have received nothing

First. Go to your dashboard and click on the ‘clipboard icon’ at the top right. Then paste that information into your original text. We really do want to know the information on your system.

Second. Where is your server located. If you are trying this from a home server your provider is probably blocking port 25. They may, or may not, open that for you. Regardless, you will never have reliable email service to a home server.

I think legit providers also block port 25 unless you use their panel to unblock it. Amazon only opens web and ssh traffic by default, I think.

for the hypothesis of the server it is a vps even it is not powerful but it is to test and get an idea on your system if it suits me I must take a powerful server of course because I have more than 40 accounts and after migrating all my data to your system
thank you for seeing the photo

All of the connection time outs would make me suspect your provider is blocking port 25. Do they have a firewall you need to configure? Not on your machine but on their side.

EDIT 0: Note that Postifix on your machine is attempting to connect to the remote servers but failing. I think that eliminates your mail stack as the culprit here.

EDIT 1: I’m pretty sure gmail would block with a valid code if they had your IP black listed. Check the headers of the queued mail for more details.

for the gmail hypothesis I don’t think so because I tried with more than just a domain to send emails and the same thing for the minling test site Email not received - mail-tester.com dont recever the mail and in addition the server and almost at birth he did not even spend 2 days no more so this hypothesis by forgetting it for the second can you help me to know if the supplier of the vps plor le por thank you very much for your time

Try sending an email between 2 different users on your Virtualmin system, doesn’t matter if they are on the same domain or not.

yes same problem no email out of domain

this might be useful

tnks but the port 25 it is OPEN

i used a little tool to talk to your server and it is responding on port 25 so SMTP is talking outside of your network.

If you recieving mail you should be able to send.
I use vultr and never had a issue.

Have you sent to anything apart from a gmail address.

I do add a reverse into vultr setting, gmail will reject if you don’t have a ptr set for both ip4 and ip6 (but the mail log should show that) like I just use mail.mydomain.com for the reverse name.
How to Create Reverse DNS in the Vultr Control Panel - Vultr.com

hello sorry for this message but I have no idea on the method that you work with but I will clarify things to you from my point of view then what you are the support you must find the problem this is the method with which I work with the cpanel team otherwise I don’t see any idea why I will change all my servers to your system
and thank you very much for your message and your ideas to help me really thank you

Can you spin up another server, clean current OS install, then install Virtualmin and don’t make ANY changes.
Add a domain and test for email working.
Something appears to be borked on your system as you can’t email between your domains which don’t leave the system so port 25 and all that stuff isn’t the problem.

Repeat, don’t make any changes or customisations before testing email.
