Admin emails not coming through
We have several cPanel servers running, and most seem fine. However, two of them don't seem to be able to send any server emails - for example, confirmation that the daily backups have run correctly. I do however get a bounce report like this:

Hello, Are the notifications sent out to a local email address, or is it sent out to an email address hosted on a remote server? If to a remote mail server, do you have root access to that remote mail server? Thank you. 0 -
Hi, Thanks for the quick response. They are going to a remote server, but we don't have root access to that unfortunately. However, I checked with the host of that server and they couldn't find any trace of the incoming email in the logs. 0 -

Hello, Search for the message ID in /var/log/exim_mainlog to see if it was sent out:exigrep MSGID /var/log/exim_mainlog

I suggest sending the notification to a local email address first, and then setting up a filter that forwards or pipes the message to the remote mail server. This should ensure the remote server accepts the message. Thank you. 0 -
Hello, Thanks for the advice, I have set this up so hopefully tomorrow morning I'll see if it has worked. However, I believe this is a wider issue with the server, as my client doesn't receive emails from the website, and they have to be routed from an external address too. I would like to try to fix the root cause of this problem if possible. Do you have any ideas? EDIT: I also just realised - the MX records for the domain in question don't point to this server, so I'm not sure if routing to a local email address on the server will work? 0 -

Check to ensure the domain name is configured with the "Remote Mail Exchanger" option via "WHM >> Edit DNS Zone" if email for the domain name is handled remotely. Thank you.0 -
OK, I've done that - thanks for the tip. I'll let you know how I get on. 0 -
Hello, I've done this but I'm still not getting any emails through, just the bounce emails. I'm a bit worried that I could miss out on any urgent server notifications. Is there anything else I can try in order to resolve this? 0 -
Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome. Thank you. 0
