Description Sönke Schwardt-Krummrich univentionstaff 2017-07-06 16:02:56 CEST
Unfortunately due to bug 42249 there is a regression regarding mail delivery to shared folder in Cyrus.

The mailPrimaryAddress of the shared folder is not rewritten within postfix to the cyrus LMTP address.
Comment 1 Sönke Schwardt-Krummrich univentionstaff 2017-07-06 17:37:10 CEST
Cause of the regression:
Address rewriting via virtual_mailbox_maps is only performed if the delivery
program 'virtual' is in use. Other delivery programs will no rewrite the
addresses. In bug 42249 the address rewriting was splitted into
virtual_alias_maps and virtual_mailbox_maps. While the latter one was (mostly) a no-op rewriting from mailPrimaryAddress to mailPrimaryAddress.

Unfortunately the rewriting for cyrus shared folders from mailPrimaryAddress to 
univentionMailSharedFolderDeliveryAddress was completely moved to virtual_mailbox_maps and was therefore no longer performed.
