Root email failing

Hi there, I just had an interesting issue where the root user of a cPanel server couldn't relay out because the callback verification method used by the relay was failing: [root@server ~]# LOG: MAIN cwd=/var/spool/exim 4 args: /usr/sbin/exim -v -Mc 1gwLXw-0002RU-Du delivering 1gwLXw-0002RU-Du Transport port=25 replaced by host-specific port=587 Connecting to mx1.relay.com [1.2.3.4]:587 ... connected SMTP<< 220 mx1.relay.com ESMTP Exim 20190214.1248 Wed, 20 Feb 2019 17:39:56 +1100 SMTP>> EHLO server.com SMTP<< 250-mx1.relay.com Hello server.com [5.6.7.8] 250-SIZE 250-8BITMIME 250-DSN 250-AUTH PLAIN LOGIN 250-STARTTLS 250 HELP SMTP>> STARTTLS SMTP<< 220 TLS go ahead SMTP>> EHLO server.com SMTP<< 250-mx1.relay.com Hello server.com [5.6.7.8] 250-SIZE 250-8BITMIME 250-DSN 250-AUTH PLAIN LOGIN 250 HELP SMTP>> MAIL FROM: SIZE=1527 SMTP<< 550-Verification failed for 550-Called: 1.2.3.4 550-Sent: RCPT TO: 550-Response: 550 root cannot accept local mail deliveries 550 Invalid sender SMTP>> QUIT I checked that mail to the hostname was allowed in "Home "Service Configuration "Exim Configuration Manager". I compared between a working server and this one and the difference was the working one had entries in /etc/localaliases. I noticed that in "Home "Server Configuration "Basic WebHost Manager" Setup" the notification email address was empty, so I added one but it didn't update the /etc/localaliases file. My questions are: - How is the /etc/localaliases file updated by the WHM interface? - Does cPanel do anything with the /root/.forward file?

Hi @plesk4lyf This is the intended behavior for mail sent to the root user, you need to set up the forward to an email account that can receive mail Both of these are edited when you set up where to forward root, cpanel and nobody's mail to. You can do this by going to WHM>>Server Contacts>>Edit System Mail Preferences Modifying where to forward roots mail updates both /etc/localaliases and /root/.forward For example on my test server:

[root@server ~]# cat /root/.forward
lauren@test.com
[root@server ~]# cat /etc/localaliases
cpanel: lauren@test.com
nobody: lauren@test.com
root: lauren@test.com

Thanks!

Hi @cPanelLauren Thanks for your post! I can see where the confusion was coming from. I always thought that "system" emails were in the "Basic WebHost Manager" Setup" area. I now see from the documentation that there are different areas of the system that are configured in the "Edit System Mail Preferences" for different kinds of notifications. Can I make the suggestion of merging Mail Preferences into Basic Setup?

Hi @plesk4lyf I'm glad it's sorted now, I agree that could definitely pose as being a bit confusing, please feel free to open a feature request for that and once it's open please add the link here so that others may vote on it as well. Thanks!
