Configuration C6

• The mail server now becomes a “mail-hub”. A “mail-hub” is often used to centralize sending, receiving and scanning e-mail messages in organizations with multiple mail servers.

• We also add a facility to send a warning e-mail to users who send messages over a certain size limit.

• Several new custom error messages and replies are added.

• For local destination addresses, we also now check that the users mailbox exists before trying to deliver an e-mail to it.
