11.4.3 Specified Route Rewriting Templates, A@B@C@D or A@B@C

The following template format works in the same way as the more common template UserTemplate%DomainTemplate@ChannelTag (note the difference in the first separator character), except that ChannelTag is inserted into the address as a source route. The message is then routed to ChannelTag:

UserTemplate@DomainTemplate@Source-Route
    @ChannelTag[controls]

The rewritten address becomes @route:user@domain. The following template is also valid:

UserTemplate@DomainTemplate@ChannelTag[controls]

For example, the following rule rewrites the address jdoe@com1 into the source-routed address @siroe.com:jdoe@com1. The channel tag becomes siroe.com:

com1 $U@com1@siroe.com
