V8 Enhancements

V8 sendmail allows envelope addresses to be rewritten separately from header addresses. This separation takes place in the delivery agent R= and S= specific rule sets, as illustrated in Figure 19-4.

V8 splits rewriting: envelope (solid) versus header (dashed)

Figure 19-4. V8 splits rewriting: envelope (solid) versus header (dashed)

The method that is used to split rewriting looks like this:

R=eset/hsetbeginning with V8
S=eset/hsetbeginning with V8

The envelope-specific rule set is the one to the left of the slash and is represented by a solid line. The header-specific rule set is to the right of the slash (R=eset/hset) and is represented by a dashed line. See R= on page 751 for a complete description of this process.
