- I would like some comments on this one.
-
- 9) What is my X.400 address?
-
- If you have an Internet address of the form username@domain.name, there
- are two alternatives for your X.400 address:
-
- EITHER there is a defined mapping onto standard attributes for your domain,
- so that, for instance
-
- Harald.Alvestrand@delab.sintef.no
-
- maps to
-
- C=no;ADMD= ;PRMD=uninett;O=sintef;OU=delab;S=Alvestrand;G=Harald
-
- OR there is no such mapping, and you will have to use a Domain Defined
- Attribute:
-
- Someone@somewhere.com
-
- maps to
-
- <Std. Attributes of a gateway>;DD.RFC-822=Someone(a)somewhere.com
-
- An IETF working document (draft-ietf-x400ops-mgtdomains-01.txt) gives
- the suggestion to use C=us;ADMD= ;PRMD=Internet to mean "any gateway to
- the Internet". This is not yet final, but might be supported on some
- X.400 services. It is not likely to work in commercial services.
-
- The following characers have special conversion rules when used in DDAs:
-
- @ -> (a) at sign
- ! -> (b) exclamation point (bang)
- % -> (p) percent sign
- _ -> (u) underscore
-
- All the hoary details may be found in RFC 1327.
-
- A few places where you can use TELNET to a port, type in your address
- and see what it maps to, are:
-
- relay.surfnet.nl(130.161.180.100) port 4545
- nic.switch.ch, login as "mailaddr"
-
- NOTE: If you use gateways that do not conform to RFC 987, RFC 1148 or
- RFC 1327, all bets are off. For instance, the kindest description of
- the result of passing through the gateways of most commercial X.400
- service providers is "interesting".
