[Dovecot] Ignoring the quota by the LDA?

Is it possible to configure dovecot in a manner that only the imap
process respects the quota, and the local delivery ignores completely
the quota? I think it should happen if I don't activate the quota
plugin in the lda section but only in the imap section.

protocol lda { ... # mail_plugins = ... }

protocol imap { ... mail_plugins = quota imap_quota ... }

Will it work or will it result in a big mess? I've the aim that a mail
will never be rejected because the recipient is over his/her quota.
