We are happy to announce a new patch release of CipherMail Webmail
Messenger. This release fixes an important issue that could
cause both the administrative and user web interfaces to become
dysfunctional ten days after their last restart. We encourage all
administrators to update their CipherMail systems as soon as possible.
You are advised to create a backup before performing the update on any
production system. The full update procedure can be found here:
You can update your CipherMail Webmail installations using the
CipherMail Console menu, or with '$ sudo dnf update' on the command
line. New virtual appliance images and package archives for offline
installation can be obtained through the support portal:
Note: if you are updating from a version prior to 4.2.2, please run the
command '$ sudo cm-run-playbook' afterwards.
Customers with a CipherMail Webmail high-availability cluster are
advised to update their cluster one node at a time. More information
about cluster updates can be found on our documentation website:
CipherMail Webmail Messenger 4.2.4 release notes:
- A recent systemd update resulted in the unexpected cleaning of
temporary files that have not been written to in at least 10 days.
Whenever this happened, the administrative web interface and user
portal would become dysfunctional until restarted. This has been
fixed by adding configuration that prevents systemd from periodically
cleaning the temporary files used by the CipherMail frontend.
