FC4 New Install : Send OK but No receive

[marcmac]

This is an lmtp failure - is this resolving to a firewall? The firewall needs to forward port 7025 to the zimbra server. (Or, is the zimbra server running the default redhat firewall? If so, you'll need to either turn it off, or allow port 7025 through.)

I have already added a port forwarding rule from my dsl modem router from port 7025 to my Zimbra box (Ip 192.168.0.5)

I will investigate to see if the FC4 firewall is indeed installed and blocking the port.

Time for a google i guess!

Happy New Year from the UK.

If you're behind a router then the firewall is only a hindrance while you're testing stuff. If you want to disable it the run System Settings -> Security Level and set the firewall to disabled. I believe that's correct for FC4 but I don't actually use that soo apologies in advance if it doesn't work.

Happy New Year to you from France.

Bon soir Bill,

I have checked the Firewall in FC4 as you have suggested and it was already disabled.

Any more thoughts or ideas from you or anyone else? I feel that it is something relatively straightforward that is not set up quite right.

Hello Matthew

Is this IP address your 'home' PC or a hosted machine? I did ask you earlier if you could telnet to that PC on port 25, does that get rejected or do you see a connection? Can you also telnet on port 7025 and see if the LMTP gives a response or not?

[marcmac]

That's a good question - can you telnet to the hostname that shows up in the error, from the zimbra box, on port 7025?

Ok here are some telnet results;-

On the Zimbra box
telnet mail.greenwayschool.co.uk 7025
trying 81.21.76.51............
timeout exceeded connection closed by foreign host.

telnet 192.168.0.5 7025 (local Ip of Zimbra box)
trying 192.168.0.5...
Connected to mail (192.168.0.5).
Escape character etc
220 mail Zimbra LMTP ready

Also tried telnet 192.168.0.5 7025 from another box on home LAN and got
220 mail Zimbra LMTP ready


Is there any way I can check to see if fetchmail is retrieving the mail ok (from the external POP3 server) and that perhaps it is not getting into the zimbra users although it has made it into the box?

How did you set-up fetchmail? I use fetchmail to get mail from my ISP and webmin to manage that sort of thing, you can run a fetchmail from webmin and see the output listed when it gets the mail and what it retrieved.

That output from telnet would indicate to me that the port is 'blocked' somewhere. You also don't have anything like SElinux on the box as well do you? Are you absolutely certain that port 7025 is forwarded through your router to the Zimbra box? What's also in your hosts file?

[marcmac]

The mail is not being delivered, since the postfix server can't access the host on it's public IP on port 7025. This is most likely a firewall issue. Can you telnet to that hostname on port 25?

Bill,

I started with a fresh install of FC4 and I think fetchmail came as part of that. I created a fetchmail.rc file in home directory. I based the file on a fetchmail.rc file that I was using successfully on a ubuntu/hula-project mail server. The file content is as follows.

poll pop.myisp.co.uk with proto POP3 and options uidl
user myusername there with password mypassword is
zimbra@schooldomain.co.uk


The following port forwards on my home router are going to the local ip of the zimbra box. 25,80,110, 7071, 7025 & 7075. Each forward is straight i.e. 25->25.

On the install I definitely chose to disable SELinux.
