Mail::Verp provides utility functions to encode and decode Variable Envelope
Return Paths (VERP) addresses, as described by http://cr.yp.to/proto/verp.txt.
.
VERP addresses are used to help manage bounces coming back from remote SMTP
servers, especially when dispatching mail for a mailing-list; the VERP address
encodes the recipient address, which can then be recovered from the bounce to
unsubscribe the address from the mailing-list.
.
The encoding uses the method described by
