mailing with qmail
There is an amazing amount of flexibility with qmail, for addressing both in the "to" and in the "from" context. That is, the manager of a qmail server can allow the users of the service, that is, those who wish to receive email in a particular fashion, to set up a wide range of addresses, and the appropriate addresses can then be used by senders.
This style of mailing is illustrated in example12.
