The qmail program is a secure, reliable, efficient simple message
|
|
transfer agent. It is meant to be a replacement for the entire
|
|
sendmail-binmail system that most UNIX hosts use.
|
|
|
|
Although qmail holds security and reliability as its top two
|
|
priorities, it is also fast. On a Pentium under BSD/OS, qmail can
|
|
easily handle 200000 separate messages per day that are injected
|
|
and must then be delivered to local mailboxes!
|
|
|
|
Security and reliability are qmail's two strengths, however. The
|
|
qmail package ensures a message, once accepted, will never be lost.
|
|
An optional new mailbox format, maildir, even lets users safely
|
|
read their mail over NFS, while still accepting new mail deliveries.
|
|
|
|
The following features are supported: host and user masquerading,
|
|
full host hiding, virtual domains, null clients, list-owner rewriting,
|
|
relay control, double-bounce recording, arbitrary RFC 822 address
|
|
lists, cross-host mailing-list loop detection, per-recipient
|
|
checkpointing, downed host backoffs, independent message retry
|
|
schedules, a drop-in sendmail replacement, and more!
