Reverse, noreverse Channel Options

Channel-specific use of address reversal
The  channel option tells the MTA that addresses in messages enqueued to the channel should be checked against and possibly modified by address reversal  (that is, modified by    controlled LDAP lookups, or the address reversal database, or the   mapping). exempts addresses in messages queued to the channel from address reversal processing. The  channel option is the default.

Note that, due to intended critical  side-effects of   LDAP lookups, side-effects that will not occur if the   channel option is used, typical Messaging Server sites should not use the   channel option.
