Courier Configuration Changes

[sparek-3]

It looks like whenever Courier is updated on a server the configuration changes that are made in:

/usr/lib/courier-imap/etc/imapd

are lost.

Is there a way to keep the changes made to this file Courier is updated?

Is there another file that these changes should be made in?

Are there specific configuration directives needing customization that are not available in WebHost Manager? Please ensure the following area in WHM is used as a first step: WHM: Main >> Service Configuration >> Mailserver Configuration

After the Courier (mail server) preferences are configured via WHM, please take a moment to examine the following YAML file that stores the Courier configuration:

/var/cpanel/courierconfig.yaml

If the desired customization is not offered in WHM, I would consider using the built-in script hooks that allow you to setup a custom "pre" and or "post" script that would be called at the beginning or end of the update process for Courier. Executed via /scripts/courierup, you may create /scripts/precourierup and or /scripts/postcourierup to perform custom actions, such as to save a backup of and or re-apply modifications to the Courier installation:

/scripts/precourierup
/scripts/postcourierup

The options look like they can be set in the WHM, but I was hoping to do this en masse for several of our servers.

I think this information will help with this.

So basically I could change the values accordingly via the WHM for one server and then copy the 2 files:

/usr/lib/courier-imap/etc/imapd
/var/cpanel/courierconfig.yaml

to the other affected servers and then those changes will keep across all of the servers even after Courier updates. Is that correct?

I think /var/cpanel/courierconfig.yaml was the missing file that I didn't know was being changed. I figured the WHM was saving the changes somewhere, but I didn't know where.

I believe you can effectively clone the Courier configuration, as setup via WHM, using the following steps:

1. Transfer a copy of /var/cpanel/courierconfig.yaml to the desired server.
2. Via shell, execute /scripts/courierup --reconfig to rebuild the Courier configuration from the YAML file.
