I've been tryng now for a couple of days to get Postfix working. The starts OK and all apears to be well and emails gererated by virtualmin get through. It's simply not listening to the internet. I have tried telnetting on port 25 and it refuses connection.
Things I have tried. I have manually changed the myhostname setup in the Webmin Server settings and changed it back again. I have also used the 'alternative' command, detailed in another post but to no avail. Looking at main.cf things like mydomain=sampledomain.tld are commented out.
I'm sure i'm missing something really simple here but can someone point me in the right direction.
