Article ID: Q93239

The mail message (.MAI) file format in Microsoft Mail versions 2.1 and 3.0 is based on the Federal Information Processing Systems (FIPS) message format described in FIPS PUB 98. This format is a subset of the CCITT X.400 standard for interpersonal messaging.

FIPS refers to the format used to store the raw data files. Vendor-defined field refers to an individual element of the message. For example, TO:, FROM:, and ATTACHMENT:, are all vendor-defined fields.
