12.6.9 Enabling Channel-Specific Use of the Reverse Database

Keywords: reverse, noreverse

The reverse keyword tells the MTA that addresses in messages queued to the channel should be checked against, and possibly modified, by the address reversal database or REVERSE mapping, if either exists. noreverse exempts addresses in messages queued to the channel from address reversal processing. The reverse keyword is the default. Refer to 10.9 To Convert Addresses from an Internal Form to a Public Form
