15 | Description: Secure, reliable, efficient, simple mail transport system | |
16 | qmail is a secure, reliable, efficient, simple message transfer agent. It | |
17 | is meant as a replacement for the entire sendmail-binmail system on typical | |
18 | Internet-connected UNIX hosts. | |
19 | . | |
20 | Reliable: qmail's straight-paper-path philosophy guarantees that a message, | |
21 | once accepted into the system, will never be lost. qmail also supports | |
22 | maildir, a new, super-reliable user mailbox format. Maildirs, unlike mbox | |
23 | files and mh folders, won't be corrupted if the system crashes during | |
24 | delivery. Even better, not only can a user safely read his mail over NFS, | |
25 | but any number of NFS clients can deliver mail to him at the same time. | |
26 | . | |
27 | Efficient: On a Pentium, qmail can easily sustain 200000 local messages per | |
28 | day---that's separate messages injected and delivered to mailboxes in a real | |
29 | test! Although remote deliveries are inherently limited by the slowness of | |
30 | DNS and SMTP, qmail overlaps 20 simultaneous deliveries by default, so it | |
31 | zooms quickly through mailing lists. | |
32 | . | |
33 | Simple: qmail is vastly smaller than any other Internet MTA. Some reasons why: | |
34 | (1) Other MTAs have separate forwarding, aliasing, and mailing list | |
35 | mechanisms. qmail has one simple forwarding mechanism that lets users handle | |
36 | their own mailing lists. | |
37 | (2) Other MTAs offer a spectrum of delivery modes, from fast+unsafe to | |
38 | slow+queued. qmail-send is instantly triggered by new items in the queue, so | |
39 | the qmail system has just one delivery mode: fast+queued. | |
40 | (3) Other MTAs include, in effect, a specialized version of inetd that | |
41 | watches the load average. qmail's design inherently limits the machine load, | |
42 | so qmail-smtpd can safely run from your system's inetd. | |
43 | . | |
44 | Replacement for sendmail: qmail supports host and user masquerading, full | |
45 | host hiding, virtual domains, null clients, list-owner rewriting, relay | |
46 | control, double-bounce recording, arbitrary RFC 822 address lists, cross-host | |
47 | mailing list loop detection, per-recipient checkpointing, downed host | |
48 | backoffs, independent message retry schedules, etc. In short, it's up to | |
49 | speed on modern MTA features. qmail also includes a drop-in ``sendmail'' | |
50 | wrapper so that it will be used transparently by your current UAs. | |

57 | Description: Source only package for building qmail binary package | |
58 | qmail is a secure Secure, reliable, efficient, simple mail transport system. | |
59 | . | |
60 | Dan Bernstein (qmail's author) only gives permission for qmail to be | |
61 | distributed in source form, or binary for by approval. This package | |
62 | has been put together to allow people to easily build a qmail binary | |
63 | package for themselves, from source. | |
64 | . | |
65 | If there is a package called qmail available, then Dan has approved the | |
66 | binary version of the package for approval, so you might as well install | |
67 | that and save yourself some effort. |
