If you send a message using a one-off X.400 address on the
To line, you may receive a non-delivery report (NDR). For example, if the mail is addressed exactly in the following format below
[x400:g=givenname;s=surname;o=exchange;p=orgname;a= ;c=us;]
the message generates the following NDR:
Your message did not reach some or all of the intended recipients.
Subject: reversed address
Sent: 5/14/01 5:24 PM
The following recipient(s) could not be reached:
'g=givenname;s=surname;o=exchange;p=orgname;a= ;c=us;' on 5/14/01 5:24 PM
The e-mail account does not exist at the organization this
message was sent to. Check the e-mail address, or contact the recipient
directly to find out the correct address.
server.domain.com #5.1.1
If the message is addressed using the more conventional format of c=us;a= ;p=, and so on, the address gets correctly resolved, and the message is delivered correctly. Therefore, if you resend the message that is addressed as follows, delivery will be successful:
[X400:c=us;a= ;p=orgname;o=exchange;s=surname;g=givenname;]
