Can't Receive Mail Using ISPConfig 3.1 on Ubuntu 18.04 Server

Greetings! I recently installed ISPConfig 3.1 onto a Ubuntu 18.04 Server installation. Everything is working except incoming email. I am a Linux novice so I will need a lot of help solving this along the way. Thank you for your assistance in advance.

 

Recent similar thread with useful ways to debug e-mail problems:
https://www.howtoforge.com/community/threads/having-issues-troubleshooting-mail.81847/

 

Thank you for the reply. I read the article you suggested and feel that is not a good fit since I can send email from [email protected], but not receive email. I am getting an error back from the addresses I used to send to [email protected] saying the server is misconfigured (see attachment). I could be wrong but I do not feel the issue is in the DNS records. Please advise me of the next steps in troubleshooting this issue.

 

I hate to ask this but I need to or we go no further. How do I get the contents of the master.cf file from a ssh terminal (using Putty) to the windows clipboard so I can paste it to this thread? I tried using nano and less and am not having any luck. The file is rather lengthy, so a screen shot is not going to do.

No noted errors in the mail logs when trying to send to the [email protected] address. Something that is curious though, when I send from [email protected] to the same address I get no errors anywhere (email client or logs) and no email shows up either.

 

Done. No errors in the logs and no feedback or errors from the email client; no email showing up either though...

 

sending to that address in roundcube did not work. Here is the end of the mail log:

I see the warning and errors but do not know what they mean.

 

I tried sending mail to that address. Looks like it arrives at you mail server, and you run graylisting. I'll wait.

 

Try Internet Search Engines with

Code:

site:howtoforge.com "warning: do not list domain" "BOTH mydestination and virtual_mailbox_domains"

 

My mail server log show my test mail was delivered to your mail server.
And got response:

Code:

<[email protected]>: unknown user: "info"
