hello all,
one or two mailboxes from the whole organization receive an infant loop of NDR (NDR Storm) when the user send a mailbox to all users.
the NDRs state that " the mailbox xxx is full" or " the mailbox yyy does not exist"
how to solve this issue? and why the email sent again and again?
not that xxx and yyy are internal mailboxes
