FC4 New Install : Send OK but No receive

[phoenix]

Hi Matthew

You've definitely got something blocking ports 25 & 7025, I can't telnet to them from here. There's a problem with your setup, does the router have a firewall and could it be blocking your connection?

I'm also slightly confused by your set-up, the DNS resolves to a different IP for mail.greenwayschool.co.uk than the error message from zimbra that you posted earlier which was for greenwayschool.co.uk. The IP at mail.greenwayschool.co.uk times out if I telnet to it and that leads me to believe there's something blocking your conection. If I telnet to port 25 at greenwayschool.co.uk there's a response from a mail server but then it gets closed. What's happening with your DNS or do you have two servers set-up?

Bill,

Here's the setup I have.

The domain www.greenwayschool.co.uk is hosted externally through the people that orginally developed the site for us.

There is a very basic webmail client that comes with the hosting but whish is inadequate for our needs. We are looking to setup a mail server (zimbra) at our school that will retrive our mail from the pop3 server where the domain is hosted. This is where the fetchmail comes in.

When someone sends an email to xxx@greenwayschool.co.uk I guess it will be sent to the domain and then picked up by fetchmail from their POP3 server by the zimbra box which will be at another site (school).


Currently for testing i have the Zimbra box here with me at home whcih is a fixed ip dsl connection with a Linksys modem/router as a firewall. Once running I will move the box to school to our dsl fixed ip address there.

How does my site (greenwayschool.co.uk) know that mail.greenwayschool.co.uk is a box at my house?

If I postqueue -p on the zimbra box I get 12 test messages from my personal email going back a few days listed.

Regards,

Matthew

You may or may not have DNS problems - but you need to get the connectivity (can't get to port 7025) solved first - take another look at your firewall, and straighten that out, and the DNS issues, if any, will be solvable.

Hi Matthew

Sorry, the DNS was a slight distraction on my part. As marc has said, the connection to port 7025 is the problem, do you have a firewall in your DSL router and if so could it be the problem? There is definitely something blocking that port.

Hi Bill & Marc,

I have had a good think about your points. I have therefore put the zimbra box into the DMZ of the dsl router at home. This should thus allow any reqd ports the relevant access.

What should I be looking for now to see whether I have progressed. I'm sure it won't all leap into life re the inbox!

Believe it or not I'm actually enjoying this experience as you really learn things.

Your continued support is appreciated.

Regards,


Matthew

You should look to see if any of the tests which were failing now succeed (can you telnet on port 7025, etc, etc.)

Marc,

Latest telnet results. Not knowing what telnetting was reqd I did a few - take your pick!

The telnets to your home external IP seemed to work, so you should be ok for the zimbra install.

Not sure why you can't get to the mail.greenwayschool.co.uk address, perhaps firewall on their end.

Mail delivery to your server should work, though.

Ok folks,

Bit snowed under at school last few days hence no reply. Also head gasket has gone on car - big expense and big hassle.

Anyway, I am still not able to receive any mail. I think that I have tried so many many little adjustments to the setup that something along the way is obvioulsy not quite right.

I am therefore going to uninstall and reinstall Zimbra.

Question. With my setup does it matter what I call my box on the install? I.e. should it be mail.greenwayschool.co.uk or mail.localhost.localdomain or just mail?

Any other pointers I should be aware of on the reinstall?

Thanks

Matthew

Hi Matthew,
My name is John, and I have just a little experence with zimbra.

You box hostname should be set to the fully qualified hostname in your mx record.

Have you tried to do a nslookup on mail.greenwayschool.co.uk ?

When I did, I got
Name: mail.greenwayschool.co.uk
Address: 81.21.76.51

Is this correct? Also, are you hosting your own DNS? If so, make sure that no other machine is named "mail".

Another question, I cannot seem to ping your above mentioned IP. Do you have ICMP turned off?

Just wonderin. I'll check back ltr. Good Luck!
