You do not need it. But it makes sending mails via a dialup connection a lot easier.

It is useful if you dial to the internet from time to time via a modem and connect to different providers, each one with a different configuration. Other MTAs are not flexible enough if you have to send mails via different mail servers for each provider. With MasqMail you can configure a different one for each provider and even set your return addresses differently.

It is also useful if you have a LAN with a gateway which is connected to the internet via a modem because you can rewrite your address depending on whether the recipients are inside or outside your LAN. So responses and delivery failures on your LAN will be sent to you without leaving it, while those outside will be delivered to your address outside. (But it does not yet send delivery failures itself yet.)

MasqMail is also often used on notebooks.

The use of MasqMail is strongly discouraged if you have a permanent connection to the internet without a firewall. First because it does not have the ability to block relaying (it relays every mail) and second because there are no capabilities to protect against SPAM. You will not take advantages of its features anyway.

Yes, for version >= 0.1.0 you can retrieve mail via the POP3 and APOP protocol from single drop mailboxes (in case you do not know about single/mutidrop, you probaby use single drop mailboxes).

You can also use fetchmail or other pop/imap clients to feed it.

Yes, there is! See here.

Set the set-user-id-bit with chmod u+s /usr/sbin/masqmail.

This means that there is already a process listening on a port, usually 25. You either have another MTA running in background (sendmail, exim, etc...) or another instance of masqmail.

It may also mean that the ports you configured MM to listen to (with 'listen_addresses') are on the same IP address, eg. you may have set your hostname to 127.0.0.1 and try to listen on localhost and your host name. In this case either set your hostname to another IP address or delete one of the conflicting entries.

You probably used the map_h_from_addresses feature in the route configuration and forgot to set your real name. The syntax is:

map_h_from_addresses = "charlie:Charlie Miller <cmiller@foo.com>";
	    

Do not forget the Charlie Miller.

In your ip-up script, you have to set read permission to the user masqmail runs as. After you write the file with the connection name, set read permission to all with chmod ugo+r file.

4.1: With connection methed file, I get the following message in the log file: "route with name name not found.".

Check whether the name in the file is really identical to name you gave to the route configuration (case sensitive!). Maybe there is a linefeed after the name in the file. Write it with echo -n.

Make sure you are using the newest version, in case of doubt search it in freshmeat. If you do, tell me. See also the section bugs on the main page.

Don't care. Tell me. Or write to the mailing list.
