At Purdue we have both Zimbra and Exchange, depending on your role in
the University.

Both systems will fail instantly if over quota and bounce a message
back.  We used to retry messages for three days in Zimbra, but we
changed that a few years ago to have both systems have the same behavior.

The only time we change that is if we are moving users from one mailbox
server to another - then we will increase the retry time temporarily for
those specific nodes.
