That is you local mailserver, obviously you have one configured.
I am trying to connect to my webhost mailserver at prime1.inleed.net .
@Joe
I do not think there are any logs since it is not even getting in contact with the mailserver but I did check just in case and there is nothing that I can see that would be relevant.
Wait a second. I see the Time is off by one hour… Correcting. And a kernel update. Rebooting. Trying again. No result.
I found something else
Webmin Actions Log > Notification email options
I checked everything just to see if it somehow triggered an smtp relay action as above and tried to save.
It gave me this error message

So maybe that is somehow relevant?
How concerned should I be about the Webmin Firewall? Or the lack of IPV6 support? Not that I want any of it.
