Drear Sirs,
Thanks for your reply,
Fully understanding the operation of the quota and emails deleted (Flag T).
I think use the plugin autocreate to create Trash folder to all users and configure webmail to automatically send emails deleted to that folder in any case my advice is that if there a method to delete emails marked with flag T into INBOX?
Thanks
Jose Luis

When calculating the quota through maildirsize did not consider the emails with flag T.
What's the point of having a quota if users can circumvent it by simply labeling their messages as "deleted"?
In all truth, if it weren't for the "expunge" command, the \Deleted label would be no different from any other label. And from that perspective, what you're asking for is essentially equivalent to a "\DoesntCount" tag, so that users can circumvent the quota by giving their messages a tag that prevents them from counting towards their quota limit. The messages *aren't* deleted; they can still be read, copied, forwarded.
What is to prevent a user from storing several gigabytes worth of "deleted" messages on your server? From that perspective, this is a security problem: any user can attack your server by creating a denial-of-service condition. They can simply store a huge number of "deleted" messages, occupying so much disk space that no other users can receive mail. Normally, a quota mechanism is supposed to protect you from this type of attack, but you're explicitly asking for a way for users to easily avoid the quota restrictions.
Dovecot is working perfectly, the problem is that as Courier had this feature,
That's not a feature, that's a security bug.
users will not purge mails
So what's the point of having a quota?
