I am new to virtualmin and I need help figuring out how to fix this problem. I have been trying to find help by searching google but I couldn't seen to understand the stuff on there. I hope someone out there can help a newbie like me.
So my main problem is I can't send email out but I can receive emails with no problem. This is the error I am getting.
