Where does cPanel store a domain's mail routing selection (automatic/local/remote/backup)?

In which file(s) does cPanel store a domain's mail routing selection (automatic/local/remote/backup) as chosen by the user in cPanel?

 

Yes, these are the final files generated by cPanel's mail routing processor, but we need to know where cPanel stores the user preference.

For example, if a user sets the preference in cPanel to 'Local' (instead of 'Automatic', 'Remote' or 'Backup'), cPanel will need to store this user preference somewhere, while also updating the /etc/localdomains file.

Then, the next time the user returns to cPanel, they will continue to see 'Local' selected, and not 'Automatic (Local)'.

So, what we need to know is where cPanel stores this data.

 

Thanks! We see the MXCHECK entries in /var/cpanel/users/$username.

But, it looks like running /scripts/checkalldomainsmxs will remove all of those MXCHECK entries in /var/cpanel/users/$username!

In other words, running that script will reset all domains on the server to 'Automatic', even if a user had selected something different.

Is this intentional, or a bug?

If it is a bug, please look into correcting the issue.

On the other hand, if it is intentional, then please perform the following:

1. Add a warning message to /scripts/checkalldomainsmxs that it will reset all domains to 'Automatic', overriding cPanel users' preferences!

2. Add an optional argument (such as --preserve-user-settings) that allows it to preserve (and honor) the users' preferences. This also speeds up the processing for domains that have user selections.
