Newbie Questions on James
I'd like to play with James and all I have is a DSL connection...
When I look at the DSL router docs it says it can forward pop and smtp servers
In the quick start... it says set the DNS Report field to the domain name.
My system reports the DSL as the DNS...
Am I right in assuming all the DSL pop and smtp configurations really do is provide a path to the service provider DNS.
So what do I need to do... if I have to phone my SP, I dont want to sound like a complete idiot... ha ha
More questions...
Say I did have a leased line with my own DNS... is there no permission required, if the DNS is set would James just cooperate with other mail servers?
I do run a dynamic DNS in the DSL router... so I do have an domain name, but a varying ip adress...
So I guess my question is how does one setup a mail server behind a DSL router... but I'm also trying to understand if permission is required from SP's before anything will work??
Thanks
Oh... another question... these mailing lists, they fantastic and I was wondering if James is the doing all this?

Thank Gary,
I think I'm finding the right things now, like discovered on the DSL router
I can set the DNS servers used, means I can point it at my SP's DNS, or any
other one, thanks for the tips.

I'm quite new to James myself, and most of my previous work has been
with postfix, but perhaps I can answer some of your questions.

This means, that your router can port forward ports 25 (smtp) and port
(110) pop to a server behind your firewall/router - a server located
within your lan. I.e. If you have a server within your network running
James (or other mail server) on an IP address (for example)
192.168.20.10 then you can configure your router to port forward port
25 (on the router) to port 25 (on the server) meaning that all the
connections which come in to your router on these ports will
automatically be sent to your server at 192.168.20.10. Same applies
for port 110

Your router probably forwards any DNS requests it received onto the
DNS server of your ISP. To the machines behind the firewall, it
appears that the DNS is the address of your router.
I've got one of my test systems set up in a similar configuration, and
the dnsserver sectuib if SAR-INF/config.xml file looks like:
<dnsserver>
<servers>
<server>192.168.90.5</server>
<server>192.168.90.1</server>
</servers>
<autodiscover>true</autodiscover>
<authoritative>false</authoritative>
<maxcachesize>50000</maxcachesize>
</dnsserver>
I have two DNS servers on this network, one of them uses the router
which gets the DNS info from the DNS server provided by my ISP.

Some ISP (in Australia) tend to block ports below 1024. However you
can often request for this block to be removed. This does not however
apply to all ISPs, the simplest thing to do is once you are set up and
have something listening on port 25 is to use a machine external to
your network to telnet back to the IP address of your router on port
25. I.e if the ISP assigned your router an IP address of:
203.123.123.245 then a simple test is: telnet 203.123.123.245 25 (with
25 being the port your are testing) and if you get a connection then
your server is up and running.

Not really sure what a "leased line" is, but in my configuration I
have no problem in James connecting to other mail servers and
delivering email, as long as it can resolve a domain name to an IP
address.

As per my config again, once the mail server is set up, then you can
simply forward all relevant ports to the IP address of your server
behind your router.

Hope this was of some help.

If you have a dynamic IP then you probably want to use an SMTP gateway
for outgoing mail (because dynamic IP are often banned from receiving
smtp servers).
You should configure your RemoteDelivery gateway to include the smtp
server name you use to send emails via your provider.
Then, if I understand your needs, you will need to configure the
"fetchmail" block to retrieve messages from your POP3 account and
deliver the mail to local james inboxes (not sure this is what you want).

I don't think you need to change the DSL router for this as long as it
doesn't block outgoing connections to POP3 and SMTP ports (and I don't
think so or you wouldn't be able to use any Mail Client).
If you want to use it for incoming mail for a given domain then it is
much more complicate because you have a dynamic ip: fetchmail is
probably much more easier and safe.

Unfortunately we are not self-hosted but we uses ASF-wide mailing list
server that is not James based.
