MX Record Setup.

What DNS records should I use to receive email? I can only receive mail from another email address hosted on the server.
Port 25 is accessable.

 

I can now receive an email from an email hosted locally but cannot receive an email from an externally hosted address what could be causing this? Port 25 is open and accessible.

 

Pretty much impossible to say with the provided information.
Try using https://www.mail-tester.com/ yourself to get some data to work with.

 

I am also unable to login to the smtp outside of my local network.
I was unable to use the tester you suggested but the ultratools returned.

MX Record Target: 1 mail.bband.net.
IP address: 212.105.162.10 (united kingdom)
Status: Connect failed
Test duration(ms): Timed out...

 

If your mail host can not be reached from the public Internet, then it can not receive e-mails.
Can you access that host in any way from outside your local network?

 

Yes, everything else is accessible externally.
Port 25 is not blocked by my isp and is showing as open.

 

That is what you must find out.
When mail is sent from the outside addressed to your mail server, is there anything happening in mail log?
The sender should receive a message if the mail is not delivered, and there should be some indication of why the delivery failed.

 

This is what it generated.

 

It was run as root.

 

I managed to mend the postfix problems now I am stuck on how to set up the Roundcube as the file in the autoinstall
/var/lib/roundcube/plugins/ispconfig3_account/config/config.inc.php is not found.

 

Did you use this tutorial?
https://www.howtoforge.com/tutorial/ispconfig-3-roundcube-plugins-on-debian-stretch/

 

I managed to get roundcube to work now it is ftp I installed pure-ftpd and ran this command
apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool
There are no errors showing in the logs but ispconfig users are not able to login as there is error 530 authentication failed.

 

Ok that is fixed. I am also getting an error in PHP myadmin only the root user works and it generates this error
Warning in ./libraries/plugin_interface.lib.php#551
