The current qmail architecture is not conducive to return path styles
beyond its basic VERP. Anything can send a VERP-message by injecting
the message with a special return path; qmail rewrites it for each
individual recipient.
Other return path styles are possible, but a message per recipient
must be injected to enforce the unique <return path, recipient> pairs
required.
Moreover, ezmlm's use of VERPs makes it easy to determine which
address is receiving list messages.
