I have been using Virtualmin without big problems. But now I am facing an issue that I cannot manage.
I have a virtual that hasn't email, but a sub domain on this virtual server has it. On this sub domain I have spam and virus filtering. All users have spam filter active. Eventhough this the 4 mailboxs don't filter anything. I check the headers of the emails received and there isn't any clause on SPAM.
Can you help me, or give me some clues to find out the problem?
Thanks in advance for any help.
