Access mapping table MTA options: access_auth (bitmask)

(New in MS 8.0) The access_auth MTA option is used to cause inclusion of additional authentication information in mapping probes. This is a bit-encoded field; currently two bits are defined. If bit 0 (value 1) is set, the value of the SMTP MAIL FROM command's AUTH parameter is included in the FROM_ACCESS mapping probe immediately following the authenticated sender address. If bit 1 (value 2) is set, the canonical username result produced by authentication is included in the FROM_ACCESS mapping probe immediately following the SMTP AUTH parameter. The default value for this option is 0.
