root @ hostname emails are frozen

[WorkinOnIt]

Hello

I can't seem to get delivery of system emails.

I have configured WHM >> Home »Server Contacts »Edit System Mail Preferences.

• The system currently forwards mail for “nobody” to “root”.
• The system currently forwards mail for “root” to “[email protected]”.
• The system currently forwards mail for “cpanel” to “root”.

I have CSF installed.

I have checked root/forward and it is showing the correct email "[email protected]"

In the mailqueue I see many frozen emails.

Output of exim

Make sure you're using a valid off server email address in these forms:
WebHost Manager »Server Contacts »Edit System Mail Preferences

A gmail account is not a great idea to use here as too many emails from your server to gmail will get them rate limited or even blocked.

 

[WorkinOnIt]

Yes, but that is not the issue here. The emails are not even getting sent.

I've also looked at /root/.forward file and the email in there is correct

Hello,

Could you verify if the hostname is missing from the /etc/localdomains file on the affected system? If so, adding the server's hostname to this file should address the issue.

Thank you.

 

[WorkinOnIt]

Hello Michael

The hostname, let's say is: myvps.myhostname.com which has been set in Home »Networking Setup »Change Hostname

Current Hostname
myvps.myhostname.com

I've checked the file /etc/localdomains and myhostname.com is listed. Do I also need to add an entry for myvps.myhostname.com ?

 

[WorkinOnIt]

Support request submitted: Support Request ID is: 7642215

 

[WorkinOnIt]

OK I added my hostname: myvps.mydomain.com into etc/localdomains

And now the problem is solved. Why is this not documented anywhere?

 

[cPanelMichael]

Hello,

The hostname is automatically added /etc/localdomains during the initial cPanel installation and anytime the hostname is changed. Could you verify if you manually changed the hostname at some point instead of using the "WHM >> Change Hostname" feature?

Thank you.

 

[WorkinOnIt]

No - I did not manually change anything - I used WHM all the way. but the hostname was missing from /etc/localdomains

I am using a cPanel ISO snapshot from my cloud provider. I have noticed a few irregular entries here and there.

I think I had better start with a fresh install next time. However, I did upgrade cPanel as a first job when getting started. I suppose it's possible any custom changes were not overwritten.

Anyway - this problem is solved.

 

[cPanelMichael]

I'm happy to see the issue is now resolved. You may also want to report the issue to your cloud provider so they can review the snapshop offered and make any corrections.

Thank you.
