Afternoon All,

 

I have managed to set up my server to receive incoming mail but do not seem to be able to send any mail, I am hoping that someone on here may have come across the same problem.

 

My domain is registered with 123-reg.co.uk

 

My ISP is Virgin Media

 

Thanks in advance for the help.

    Hi,

     

    Can we get some more details? This is all very vague. What client are you using to send mail? What happens when you try to send a message? What do the logs say?

    Well, you need to check the logs to be sure that SMTP is running: Server.app => Status => Logs => Mail. Look for any information about SMTP.

     

    The implication is that either your mail clients are configured incorrectly and not accessing the SMTP server on the correct port, or that your SMTP server is not operational. The ports for SMTP are 25, 465 and 587. Are you familiar with tools such as nmap or even using telnet to check the availability of a port?

    To add to jaimie's advice dns has to be working with an entry for your smtp server as well, both internally and externally

     

    Setting up each mail account with your ISP kinda defeats the object of running your own mail server

    Something is not right

    That's completely unrelated. You need to ask your ISP if they block SMTP ports and if they allow 3rd party mailservers to run over their network.

     

    Also, you need to verify that SMTP is running on your server. In terms of logs, did you verify that mail service is running? Do the mail logs show any SMTP errrors? It's not like we can tell you to look for a particular thing. You have to learn to debug problems by reading, googling, etc.

     

    Do you know how to use telnet? Do you know how to use a portscanner such as NMAP?

    You should be using your server's SMTP. That's the whole point of running a mail server.

     

    What happens if you type the following on a client machine...

     

    telnet your.server.com 25

    and you connected from a machine that is not your server? If so, this is good news. That means the service is responding. Now, on that same machine you tested from, open Mail.app and configure an account to connect to the server per usual. Go into the SMTP settings for the account and make sure that the SMTP port is 25 (you can check the button that lets you use all three actually). Now, in Mail.app, go to Window => Connection Doctor and run a test. What are the results?

    Ok, now try sending a message from that machine.
