Topic: SME server behind router: no mail!

[Stewart]

I put my SME server behind a Linksys router. Primarily I did this to take the load off the Pentium II-233 that houses the server. Now all it is going to do is serve up web pages, and be my mail server.

I'm able to serve up web pages, and people can get in to the website. I can even send e-mails from my internal network (which involves traffic going out to the router, then down to the SME server box.  

But, my SME Server box is not receiving any mail on its mail server.  

How should I change my mail settings to allow SME server to run behind a router?

Alternatively, maybe my old hardware can keep up with the traffic from the 3 home network PCs, and I should just return to the previous configuration, with the SME server being server, firewall for all internal workstations?

YOu can read about my network configurations at http://midtoad.is-a-geek.org/

You're almost always better off without a separate "router", unless you have some specific need which can only be satisfied with one (which is unlikely).  However, your immediate problem can probably be solved by opening port 25 on your router.

We're using a 225MHz Cyrix here for a LAN of about 15 users. It's not the fastest thing ever obviously, but I don't think it slows down surfing at all. As has been stated many times in the past, taking the router out of the equation will let the SME work exactly as designed (i.e. no need for traffic to double back from the router and stuff like that), and it avoids unnecessary configuration of a bunch of extra stuff.

Hi Dan,
I have a simular problem except that I have a SME 5.6u3 set up as a test machine in server only mode and my main server is a SME 5.5, this does all the normal network stuff but I would like to receive email from a couple of different pop3 addresses on the test server, I have installed the Vincent Filali fetchmail addon (which works fine on the main server) and I cannot get any mail, I have also uninstalled the fetchmail addon and still no mail, so could I open port 25 on the main server? Would this be easy and would it compromise the firewall? The test server connects to the internet if I use the test option in the server console.
Any help or advice would be appreciated.
Regards,
Del

thanks for your comment.   I have indeed taken the router out of the equation. It was just complicating matters too much.  I put back the SME server back in as gateway and server, hooked up a 5-port hub to it, and all my workstations are back in action.   As you say, the router just complicates matters.

Port 25 (SMTP) is for sending mail. You only need to open/forward it if the DNS record for the domain has your test server listed as the MX. If you just want to pull mail from other accounts, it uses the standard POP port, 110.

Thanks Bill. I will keep trying it.
