Routelocal Channel Option

Short circuiting rewriting of routing addresses
The  channel option causes the MTA, when rewriting an address to the channel, to attempt to "short circuit" any explicit routing in the address. Explicitly routed addresses (using !, %, or @ characters, or with an address embedded within quotes as the local-part of the address) will be simplified. (The "l" channel defaults to   behavior.)

For instance, if domain.com is a domain that rewrites to a channel marked with the  channel option, then any of the addresses somewhere.else.com!user@domain.com user%somewhere.else.com@domain.com @domain.com:user@somewhere.else.com "user@somewhere.else.com"@domain.com will be rewritten to simply.

Use of this keyword on "internal" channels, such as internal TCP/IP channels, can potentially allow simpler configuration of  SMTP relay blocking.

However, note that this option should not be used on channels that may require explicit    source routing or other routing, such as typical Oracle Messaging Server MTA internal TCP/IP channels.
