APPLIES TO


 * Microsoft Mail Gateway to X.400 3.2

-



This article was previously published under Q194548



SYMPTOMS
If the Microsoft Mail Gateway to X.400 sends a message with a free-form name that is longer than 64 characters to a foreign system, the message transfer agent (MTA) on the foreign system may indicate that it cannot deliver the message because the free-form name is invalid.



CAUSE
The Microsoft Mail Gateway to X.400 normally uses the contents of the personal name (PN) field to create the free-form name. However, if the PN field is empty, the entire X.400 address is used to create the free-form name. When this occurs, it is possible for the free-form name to be longer than 64 characters.

The NIST Stable Implementation Agreements for Open Systems Interconnection Protocols specify that the maximum length for free-form names is 64 characters. Therefore, some foreign systems are unable to process messages with free-form names that are longer than 64 characters.
