Topic: 5.6 collecting Demon POP3

[Innes Lange]

I have recently converted my Demon Internet connection from the good old 56k modem to the ADSL. One minor problem that I have run into is that Demon do not push the mail to their ADSL users. So am now trying to get the SME server to collect all the mail for a domain through POP3.

This seems to work okay for mail directed user e-mail address, but as the documentation says, it barfs pretty well on the mailing list stuff.

Does any one have any ideas of how to get around this issue. I have seen from the headers that Demon is able to determine who it is for. Under SMTP delivery everything worked fine.

Thank you for your help in advance.

They do kick mail to adsl in Holland. Are you sure? Here it is an option you can activate on there supportsite...

hope this works?

I have confirmed that it is not an option in the UK. I got around it by
using the templates-custom system.

Create /etc/e-smith/templates-custom/etc/fetchmail
copy /etc/e-smith/templates/etc/fetchmail/50multi-drop to the above
directory

edit the file in the new location, find $OUT .= "    protocol POP3\n";
then add a line that has the following $OUT .= "    aka mailstore\n";
save and exit terminal
then set-up the multidrop as per usual. The template system will use the
custom template, and that line "aka mailstore" makes it use the header
section that contains "mailstore" were it can pick up a deliverable
address from.

Hope that helps someone else. It is definitely a flaw with Demon ADSL,
and not the SME-Server.

Hi Innes,

Your post got me curious.

Is Demon your domain host ? Does Demon block the SMTP ports to their ADSL subcribers ?

If Demon does not block SMTP traffic, and is also your Domain host, consider moving your DNS hosting to someone else like Zoneedit. SMTP mail delivery has nothing to do with your ISP unless your ISP is blocking SMTP traffic.

When someone sends you mail, their mail server checks the DNS to see where to send mail to for mails going to your domain. If the DNS says to send it to your SME server (which resolves to an IP address down the track), the sender's mail server will do so (again, nothing to do with your ISP unless your ISP blocks SMTP traffic).

The problem was that my home e-mail was through the lange-nairne.demon.co.uk "domain" and demon are the mailhost for these domains. They deliver the mail through SMTP on the dial-up accounts, but not ADSL. Though Demon (NL) does allow its customers to opt into SMTP delivery.

As the SME server is behind a firewall on a private network, I was not fond ogf the idea of opening the server to the internet. I am of the belief that I enjoy a bit of security having Demon front my mail paths.

Otherwise yes I could have just had another domian's mail routed direct to the SME Server.

Demon SMTP is not quite standard. When you use dialup you authenticate to their Radius server which notifies the "punts" that you are on line and triggers an SMTP connect for mail delivery.

If you convert to ADSL with static IP's in the "no nat" option and have a proper domain with them they will reconfigure mail to go to your designated IP via SMTP with back up MX records pointing to their store & forward relays. No authentication is used.

If you have a user.demon.co.uk style domain you are stuck with POP3 - you need to configure a fetchmail script which declares itself as a multi drop, declares the domains etc

Just like to say that the addition of the  "aka mailstore" line works great for me. I use Demon as a backup ISP for wireless broadband but still collect mail from Demon via the broadband link as the wireless ISP only has a poor webmail interface.  The SMTP "push" feed doesn't work unless you connect  directly to Demon.

Thank you, so simple.

Cheers
Dave.
