I've been trying for some days now, but till now with no luck.
In ISPconfig I've got a domain www.somename.com
(lets call this server server_1).
The website and DNS is running on this ISPconfig server (server_1), but the email for that domain is on an other server (lets call it server_2)
Within ISPconfig (server 1) I've created the domain www.somename.com
For the domain www.somename.com
I've enabled Create DNS.
I've also created an user & email as I needed it to FTP to the site.
I also set the Mailserver (under the tab options) to External Mailserver.
In the DNS for domainname.com I've setthe MX record to an A record that points to the server that is used for mail.
When I email with a user account that does run on the ISPconfig (server_1) to somename.com, the mail will not go to server_2 (it get an error saying "Your message did not reach some or all of the intended recipients. Recipient address rejected: User unknown in local recipient table"
(note that this is only when I use an email account that is on server_1)
Looking at /etc/postfix/local-host-names it does still show somename.com
Should the option "External Mailserver" not remove this from the local-host-names file?
When I use an account that is NOT running op server_1, mail (gmail, hotmail etc... ) all is working fine for somename.com
Anyone here who might know what is going on?
