KB108732 - X400: Address Syntax

SUMMARY

All address attributes may be separated by semicolons (;). For example:

c=US;a=TELENET;p=ABC;o=P/Q;g=JOHN;s=STEEL

All address attributes may be separated by a forward slash (/). A leading forward slash is also required at the beginning of the O/R name. If a forward slash is part of an address attribute, the forward slash must be preceded by the escape character ($) and is entered as $/. For example:

/c=US/a=TELENET/p=ABC/o=P$/Q/g=JOHN/s=STEEL

Characters

The characters allowed in an X.400 address is the printable string of characters defined in the X.409 specification.
