Problems on System Email

[CoreXL]

Hello good evening, I am having a problem on my server and it is that the emails related to the system are not arriving correctly, since the email address does not appear.
Currently I use sendgrid's SMTP Relay and all the emails from the accounts that are on the server work perfectly.

The only fault I see is that all the emails that are related to the system, such as updates, execution of cron tasks, etc., do not reach the email that I have set as a receiver.

I was looking at the activities of the emails and they appear like this:

To	[email protected]
From	[email protected]
Subject	lfd on testsaur: blocked 120.92.139.183 (-)

If you look at it, the email you send does not show the full address of the hostname which should be: [email protected]
I deduce that the emails are not reaching me because the address does not appear complete.

How can I correct this problem?

Hey there! That's definitely odd, as mine show as the full [email protected] address when I check the mail delivery reports. If you check that page in WHM, does it show the full hostname listed there? Is it possible your hostname has reset at some point? If you just enter "hostname" into an SSH prompt it will return what the operating system thinks the current hostname is set to.

Hello, indeed in the Mail Delivery Reports, the full email address does not appear, it appears only as I mentioned it at the beginning of the thread.
It looks like this: [email protected]

This has never happened to me before.

I have executed the command to know the hostname I had and it appears like this:

hostnamectl status

The result was the following:

[[email protected] ~]# hostnamectl status
Static hostname: testsaur

So I went to look at the configuration inside WHM - Change Hostname



And it appears to me like this, however I have given the Change again, and then I have rerun the hostnamectl status command and this is the result:

[[email protected] ~]# hostnamectl status
Static hostname: testsaur.privatedomain.com

Now I have gone back to the Mail Delivery Reports and the full email address appears: [email protected]
But I get the following error: root cannot accept local mail deliveries



Thanks in advance.

Are you hosted on Amazon or Google? Some providers reset the hostname if the server reboots, and there is an additional script that needs to be created in order to make sure that survives a reboot.

Hello, at the moment I think it already works: root cannot accept local mail deliveries

I have added a full email address in:

cat /etc/localaliases
cat /root/.forward
