I have been running Cyrus-imap and ISPconfig3 for 2 years now in production.
But still some small things are annoying and could easily be fixed.
As long as ISPconfig3 does not support Cyrus-map, the mail config tabs "Autoresponder", "Mail filter" and "Custom rules" are presented to users but of course do not work.
A quick fix would be to be able to disable these tabs in the configuration.
The cleanest way would be if these tabs would correspond with limits that would cause the tab to disappear if the limit value is "0".
I provide the "Autoresponder", "Mail filter" and "Custom rules" functionality to the users though the webmail client as long as ISPconfig does not support Cyrus-imap and it's Sieve filtering daemon.
But much nicer would be if Cyrus-imap would be supported.
I see similar requests concerning Dovecot, hopefully this could mean that the "disable" option would come available and that the sieve support will also be useful for Cyrus.
"Disable unsupported mailbox traffic statistic in case of dovecot mailserver"
"FS#1352 - Modify where sieve scripts are saved."
Thanks in advance.
