I had Magento running on a shared server (hostgater) till I found out that I did not have root access and could not change the php level and various other things. So i cancled my hosting, bought a server and now... I am running Magento 2.2.3 on a fully updated Centos7 in a VM in esxi. (yes I am an IT guy) So my question is what is the best way to set up a mail server with Magento. I think i read somewhere that magento uses php for mail. If that is the case would sendmail be the best option? So my main goal is to have the email come from email@example.com. I am pretty sure that the mail server would have to be installed on the same os and vm as magento correct?
