Is it possible to clean the trash folder automatic?

The above "purgetrash" event is not recursive.  It should only operate
on user/*/Trash (INBOX/Trash, from the user's point of view).
Mailboxes fitting the pattern, "user/%/Trash/SPAM" would be untouched.

One advantage of this method is that it will work on any mailbox that
matches the "user/%/Trash".

One disadvantage is that it will operate on "user/%/Trash" without the
possibility of any exceptions.

cyr_expire does the work of purging messages that have expired (see the
man page for cyr_expire for more details).  It is usually configured as
an event in cyrus.conf.

I think this is probably the more graceful solution (using mboxcfg to
set expiration flags in the box's metadata).   You can use the mboxcfg
command within cyradm to recursively set the expire annotation on a
large range of mailboxes.

One disadvantage of this method is that the expire annotation will not
be automatically applied to new accounts' Trash folders.  You might need
to integrate the expire annotation into your account creation routines.

One advantage of using the expire annotation is that users can
potentially specify how long they want mail in the specified mailbox to
hang around before it expires (or if they want mail in the specified
folder to expire at all!).  For end users a web based interface to make
these tweaks would probably be preferable.

These are, of course, only my opinions.
