With this Zimlet installed you can enable automated replies based on a filter from within your Zimbra Web Mail.
While you could always configure Zimbra filters to send automated replies over CLI using:
/opt/zimbra/bin/zmmailbox -z -m firstname.lastname@example.org afrl "Filter_name"
active any address "to,cc" all is "email@example.com" reply "Auto reply message" stop
This feature was not available to the end user in the Web Interface. This Zimlet adds a button in Preferences -> Filters -> Create Filter to add this functionality. https://github.com/Zimbra-Community/reply-by-filter
We have completed the Survey Monkey and the winner is Zimbra FOSS Two Factor authentication.
Based on the survey our initial focus will be Zimbra FOSS 2FA and that will probably be based on PrivacyIDEA and PrivacyIDEA LDAP proxy and will probably be made available via dockerhub.
