Re-run the install steps above when upgrading the Zimlet to newer versions, only for upgrades you can also run the following to flush the server cache:

zmprov fc all
zmmailboxdctl restart

Keep in mind the browser cache, if upgrading does not work, use an incognito browser tab, or flush browser cache.

RMail has an option (RPX) to wrap emails in encrypted PDF's, by default, Zimbra does not allow them to pass the antivirus filter. You can enable encrypted PDF's like this:

 su zimbra
 zmprov mcf zimbraVirusBlockEncryptedArchive FALSE
 zmclamdctl restart

This is optional , see Configurable options below on what you can configure.

To change the default configuration, you can change config_template.xml like this, you must have installed the zimlet before configuring (steps above):

su zimbra
zmzimletctl getConfigTemplate com_rpost_rmail.zip
nano config_template.xml  # make your changes
zmzimletctl configure config_template.xml

Configurable options

su zimbra
zmzimletctl undeploy com_rpost_rmail
