4 Masqmail is a mail server designed for hosts that are not permanently
|
|
meillo@0
|
5 connected to the internet. It handles outgoing messages, i.e. those
|
|
meillo@0
|
6 that are to be sent over the non-permanent link (usually a ppp or slip
|
|
meillo@0
|
7 connection over a modem or ISDN adapter) specially and delivers them
|
|
meillo@0
|
8 only when explicitely told to do so. There is support for multiple
|
|
meillo@0
|
9 providers, it is possible to write different configurations for each
|
|
meillo@0
|
10 one. The configuration chosen is selected at delivery time, so that if
|
|
meillo@0
|
11 for example a delivery of a message failed while connected with
|
|
meillo@0
|
12 provider 1, it may be delivered when connected to provider 2. For each
|
|
meillo@0
|
13 provider another mail host (or none) can be specified.
|
|
meillo@0
|
14
|
|
meillo@67
|
15 Masqmail provides (a yet simple) mechanism to rewrite headers, also
|
|
meillo@0
|
16 depending on the current connection. This makes it possible to deliver
|
|
meillo@0
|
17 messages with a return address on the local network which will be
|
|
meillo@0
|
18 rewitten at delivery time. The purpose of this is:
|
|
meillo@0
|
19
|
|
meillo@0
|
20 - to allow delivery failure messages that are produced on the local
|
|
meillo@0
|
21 network to be delivered immediately, while those that are produced
|
|
meillo@0
|
22 outside can be delivered to a mailbox on the internet, to be retrieved
|
|
meillo@0
|
23 later.
|
|
meillo@0
|
24
|
|
meillo@0
|
25 - to give mail servers a return address which they can accept if they
|
|
meillo@0
|
26 check for spam mail. Many mail servers require a return address which
|
|
meillo@0
|
27 has the same domain as the server it is getting the message from. If
|
|
meillo@0
|
28 you normally connect to only one provider, this is usually not a
|
|
meillo@0
|
29 problem as you can configure your mailer to a fixed address (but then
|
|
meillo@0
|
30 there is still the problem with the failure messages...), but it is a
|
|
meillo@0
|
31 problem if you use different ones from time to time.

|
33 Masqmail shall once be a complete replacement for sendmail (or other
|
|
meillo@0
|
34 MTAs such as exim, qmail or smail) on a local network, but it is NOT
|
|
meillo@0
|
35 supposed to be installed in a network with a permanent internet
|
|
meillo@0
|
36 connection (at least if it is not behind a secure firewall) because
|
|
meillo@0
|
37 it has no ability to check for undesired relaying or spam filtering.
