[Dovecot] Bounce messages

[Thanh Long DANG]

Hi,

The problem is : when the mailbox is full and i'm trying to send a mail to it from another mailbox :
1- the server rejects the mail (OK)
2- need to notify the sender that the mailbox of recipient is full (Not OK)

(quota notifications is ok)

I think the link may help me. I will have a look today.

Kind regards,
Long
