Over quota, or Disk quota exceeded
Example:
Recipient address: user@ims-ms-daemon
Original address: user@host.tufts.edu
Reason: Over quota
This error means that the recipient is temporarily unable to receive email because their email inbox is full. If the message is urgent, you should attempt to contact the recipient by other means. If the message is not urgent, resend the message at a later time.
Unrouteable address
Example:
user@host.com
Unrouteable address
The listed address is not valid. This error usually occurs when the address contains an invalid domain name, which the mail servers are unable to route. Please verify that the address is correct and resend the message.
Relay not permitted
The host refused to relay mail to a third party. Generally, this means that you are attempting to use the Tufts mail relays from off campus, and sending to a non-Tufts email address. To do so requires you to authenticate first.
Please see the TLS/Auth section below for more information regarding authenticating.
Relay Upgrade
TLS/Auth
Users will now be able to use the Tufts mail relays from offsite, providing that they setup their email client to do so. The first thing users must do is to enable SSL/TLS (using an encrypted connection) in their email client. The relays will NOT allow AUTH attempts without a secure connection (SSL/TLS). Once SSL/TLS is enabled, users need to configure their email client with a username/password (UTLN / Trumpeter password) for the outgoing mail server.
