By default create & subscribe only to \Junk with name "Spam".

Commit: 60737

Adds UCRVs:
* mail/dovecot/mailboxes/special/*
* mail/dovecot/mailboxes/auto/*

When installing/updating the special-use tags are assigned to the following folders:

* Drafts → \Drafts
* Junk → \Junk
* Spam → \Junk
* Trash → \Trash
* Sent → \Sent
* 'Sent Messages' → \Sent

By default no folders are autosubscribed.

OX-integration can use this to autocreate+autosubscribe to:
* Spam → \Junk (special-use tag is already set by default, but folder is not created and subscribed to)
* "Gesendete Objekte" → \Sent

by setting

* mail/dovecot/mailboxes/special/Spam="\Junk"
* "mail/dovecot/mailboxes/special/Gesendete Objekte"="\Sent"
* mail/dovecot/mailboxes/auto/Spam=subscribe
* "mail/dovecot/mailboxes/auto/Gesendete Objekte"=subscribe

r60821: auto create and subscribe to "Ham" and "Spam" folders in default installation
Comment 4 Sönke Schwardt-Krummrich univentionstaff 2015-06-22 13:42:16 CEST
Added here, because it is part of the new code:
if UCR variable mail/dovecot/folder/{spam,ham} is set to the empty string, funny things may happen → in cyrus the value "none" disables the spam folder. I think, that the empty value (ucr set mail/dovecot/folder/="" → variable is not unset!) should also disable the spam/ham folder.
Comment 5 Daniel Tröder univentionstaff 2015-06-22 17:47:15 CEST
Commit 61405:
* If the UCRVs are unset or set to "none", no directory will be created. But if they are set, users will automatically be subscribed to them, unless mail/dovecot/mailboxes/auto/<folder>=none.
* mail/dovecot/folder/{spam,ham} are now set in postinst: mail/dovecot/folder/ham?Ham mail/dovecot/folder/spam?Spam
Comment 6 Daniel Tröder univentionstaff 2015-06-23 18:08:22 CEST
Commit 61429 adds more descriptive text for the UCRVs.

→ REOPEN → please do not use sys.exit() in UCR templates, otherwise the UCR process will not work like expected
