I added a second site to my virtualmin box with its own IP address.
For some reason when email is sent to the new domain/IP postfix refused the connection to 25.
If i set the mail server for the new domain to the host domain mail.1stdomain.com it works, mail.2nddomain.com does not work with:
error: (postfix/smtp: connect to mail.2nddomain.com[1xx.xxx.xxx.xxx]:25: Connection refused
postfix is set to receive on all connections.
Any help would be appreciated!
