I was just exploring some features of virtualmin, i did not change anything. I just went into spamassasin settings and updates the allow list and added couple to deny list. Other than that i went to Virtualmin>system settings >re-check configuration. it told me your system is not ready for virtualmin (at this point the system was working fine) It had asked me to update the DNS list, so i added 220.127.116.11 in there along with the default gateway. Also it says you should disable BIND so i tried to uncheck it from module list but it didnt let me. so after that i am unable to receive emails, i can send them. but i can not get them, before when i was trying to send from hotmail i was getting the following error
This is the mail system at host domain.local.

The mail system
<user.domain@Email> (expanded from <email@example.com>): Host or domain name
not found. Name service error for name=Email type=A: Host not found
so then i changed the hostname to domain.ca and then when i send email from hotmail i do not get undeliverd mail error but i dont get the email at the other end either.
PS: i think i somehow screwed up the dns :(
