If you have an email problem the chances of it being related to Postfix are pretty close to 0%. Please be specific about the problem you are having. We have seen a lot of provider issues lately and people refuse to accept the correct answer when given so we need specific problems.
with what I must specify the problem exactly but what I do I have to restart the server each time and empty the pending emails and restart the postfix so that I receive an email or two max for the info I am talking on a vps which manages 10 domain and every hour can reach almost 5000 emails
That doesn’t make sense. It’s crazy to look at a problem you don’t understand and say, “I want to replace this thing I don’t understand with some other thing I don’t understand and have to ask for help to even find this other thing I don’t understand.”
That other thing would be Sendmail (or exim, though Virtualmin doesn’t support exim directly), and I guarantee you can’t make those work, if you’re having trouble with Postfix.
dear Mr joe I am disappointed I tried to contact you directly I am talking to staff it has been 3 days since I formatted my server and I installed virtualmin and I paid for my second license and the emails are not working I contacted Ilia and Eric didn’t respond and I’m in trouble because I have this problem tomorrow it’s Monday and all the clients have to work with their emails so I reformatted the vps and I installed the new cpanel and now I’m in the process really restores everything I am disappointed here is my log file.
