Roundcube issue - mail missing

To both Serra and manokiss, does the same issue occur when using SquirrelMail and Horde? This may or may not be an issue within Roundcube and how it caches data; the Roundcube cache is not controlled by cPanel.

What is the IMAP/POP3 server in-use on the system? The following command will show the current setup (please copy and paste the output):

Code:

# /scripts/setupmailserver --current

 

To help gather more detail about the Roundcube issue, please provide the output from the following commands via root SSH access:

Code:

# grep '' /etc/*release /var/cpanel/envtype
# grep '' /usr/local/cpanel/version /var/cpanel/roundcube/version
# grep roundcube_db /var/cpanel/cpanel.config
# /scripts/setupmailserver --current

Additionally, it will help to know the following:
1.) Are the messages that appear missing always newly received, or is it affecting significantly older messages already existing in the Inbox?
2.) Do the messages display after the following two steps?
2.A) Log-out of Roundcube (via the Log-out link in Roundcube and not by closing the tab or window)
2.B) Clear/flush the browser cache and close all browser windows
3.) Is there any change in behavior after using Roundcube to compact the Inbox (and any other affected folders) and then re-performing step 2?

Please note that Roundcube is a third-party product and would depend on the vendor for issuing official patches; I don't have enough information to know which Roundcube bug might be involved, but if you have any details in this regard we would like to know.

For reference, cPanel version 11.25 uses the latest stable release of Roundcube version series 0.3. Per internal case ID #35890 there is a minor Roundcube version update queued for Quality Assurance testing in the cPanel/WHM BETA build tree; however, when I checked the official Roundcube change log for this minor version update it was not unquestionably clear to me if it would help the specific issue being encountered. For reference, here is a link to the Roundcube change log: Change Log - Roundcube Webmail

Here are a few additional resources for researching that I suggest:

The symptoms described lead me to believe it may be related to issues surrounding the caching that is performed by Roundcube.

To help narrow the possible causes I would suggest to temporarily disable Roundcube caching to see if the issue still occurs.

The following configuration file is used to toggle caching on ("TRUE") or off ("FALSE"):

Code:

/usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

To check if caching is enabled or disabled, the following command may be used (via root SSH access):

Code:

# grep enable_caching /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

Here is a set of steps that can be used to disable caching temporarily:

Code:

# cd /usr/local/cpanel/base/3rdparty/roundcube/config/
# cp -pv main.inc.php main.inc.php.backup
# perl -p -i -e 's/^\$rcmail_config.*enable_caching.*TRUE\;/\$rcmail_config\[''\'\''enable_caching''\'\'']\ \=\ FALSE\;/g' main.inc.php

To re-enable caching all that is needed is to restore from the saved backup copy of the original configuration file, as seen below:

Code:

# cd /usr/local/cpanel/base/3rdparty/roundcube/config/
# cp -pv main.inc.php.backup main.inc.php

 

Automate Roundcube configuration customization via cPanel and WHM script hooks

Thank you for the feedback and information. As was suggested by Craigles, it is possible to automate customizations after an update using the built-in script hooks, such as preupcp and postupcp. For additional clarification please reference the following documentation:

• Hooking into cPanel Functionality
• cPanel/WHM Script Hooks

For purposes of automation in a custom script using the built-in hooks (e.g., "/scripts/postupcp"), I would revise the suggestion to the following example that I believe should work with minimal difficulty:

Code:

#!/bin/sh
/bin/echo
/bin/echo "Post script running..."

/bin/cp -fpv /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php.backup

/usr/bin/perl -p -i -e 's/^\$rcmail_config.*enable_caching.*TRUE\;/\$rcmail_config\[''\'\''enable_caching''\'\'']\ \=\ FALSE\;/g' /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

/bin/echo "Post script completed..."
/bin/echo

 

To the best of my knowledge I believe that caching in Roundcube is now disabled by default, at least I see it is disabled when forcefully re-installing Roundcube in cPanel & WHM version 11.28. As the IMAP/POP mail server, Courier or Dovecot, is hosted locally, that is in the same system that serves cPanel, I believe that Webmail should not require additional caching in Roundcube over what is already handled by the local mail server.
