Incoming Mail Server Setup
Posted on 2012-08-28
As part of an Alfresco setup, I have enabled the incoming mail server. I'm having some issues with the configuration that I hope someone can help me with. I am new the the work of mail servers, so please bear with any stupid questions!
Setup is on a CentOS box hosted by Rackspace.
I have run the following tests. Part of my domain name has been changed to 'example' for the purpose of this post.
My alfresco mail server configuration:
If I telnet the following:
"telnet localhost 25" I get the following message which indicates (to me at least) that the server is up and running.
"220 EXAMPLE-ALFRESCO.localdomain ESMTP Postfix"
However, if I telnet the following:
"telnet doc.example.co.uk 25" from the server then I get the following:
"telnet: connect to address xx.xxx.xxx.xx: Connection refused
I also cannot establish the connection if I telnet the above from my PC over the internet although I can telnet the FTP service running on port 21.
I have created a MX DNS record as follows:
Domain Name: example.co.uk
TTL: 300 seconds
(Priority set to 10)
I realise that there are probably multiple places where I could have gone wrong with the setup and configuration, but it would be good if someone can point me in the right direction on how I can solve this connection issue.
