A Damaged Contact Within a Distribution ListA damaged contact within a distribution list (DL) can create an NDR when sending an e-mail message to a distribution list.

The damaged contact will need to be deleted and re-created (see the following section for creating a new contact.)

Mail Server Expects Addresses to Be in Angle BracketsSome SMTP servers require that addresses be enclosed in angle brackets. This is particularly true for older mail server systems. In addition, your e-mail name, which is defined in the Internet e-mail information service properties, must also be enclosed in angle brackets.
For example, the e-mail addresses should have this format:
<firstname.lastname@example.org>Check with your Internet Service Provider (ISP) for their addressing requirements. For other people with newer servers to be able to reply to your messages, you must type your e-mail name in the Reply Name box without angle brackets.
Unrecognized IP AddressThis can occur if you connect to the Internet using one service provider (ISP), and attempt to send e-mail through a different ISP's mail server. The error is an attempt to prevent the sending of junk mail (SPAM). The only solution is to send e-mail using the mail server of the active connection.
