I have… Debian 10, virtualmin 6.1.5…
Well…
I don’t know exactly from where to start… all worked ok - before being “target” of spam - finally found the account exposed and used for sending emails to others… and of course deleted because was using a very simple pass…
So then I’ve decided to make more speed my server and check that logs coming up to 4GB+ +so change the log rotation…
Reboot my vps… and then after all i can’t receive mails… i can send to some external domains but not to mine… (#$#@$##)
I get from mail client when i sent from other domain this:
This is the mail system at host ooo******.xx.
