Unable to send messages

[Sultan Ghaznawi]

Hi Nathanael,

 

Many thanks for your response. What you are suggesting is what I thought of at the first place, however, I can ping any IP address from that box without a problem and all other tools, such as yum, curl, wget and everything else works. It seems the DNS is also set up properly, the only thing that might be an issue is if for some reason the firewall within the box is rejecting outbound requests from this application on a specific port. I did run the port white-listing command before installing Kolab.

 

Any other suggestions?

 

Sultan

Hi Everyone,

 

I set up the Kolab 16 on CentOS 7 and everything went well. Here is what is happening:

 

1.       I can send/receive emails between internal users (my domain within the box).

2.       I can receive emails sent from outside my domain over the internet

3.       I am unable to send out messages. I send a message, I do not get an error in the UI, the /var/log/maillog shows “network is unreachable” and “timed out” messages. I ran the “lmtptest  <http://google.com/> google.com” command and it shows network unreachable error.

 

It sounds like the error is completely unrelated to kolab. Can the server successfully resolve names? Does its default route work outbound? Can you grab websites using curl or wget on that server? A network unreachable error really seems unrelated to kolab or any server system at all. Try narrowing down the issue. Perhaps dig apple.com to see if you get an IP etc..
