We have a problem with sending out mails with a php -script for mailadressess with firstname.lastname@example.org
The customer is using a different mailsolution than ISPConfig.
During the creation of the site the Local/External Mailserver was set to
Local Mailserver in ISP Site/Options and we changed it afterwards, but no
Looking at /var/log/mail.log confirms that the relay is local and ISPConfig / Postfix is not doing a MX check for this domain.
What can we do to fix this ?
We are running IspConfig 2.2.19 and thank You for a great hosting platform.
