Hi i am freelancer web developer (and Linux sysadmin) i get domain for me for business use (by my name unlike other domains i have) i already have email server for installed in my server but here the question: Is hosting the mail server on google or outlook is better than self host for spam, availability and email, reachability for business usage. As some of you may know in contracts email used as official way to communication and it's must work as expected TL;DR: For business use is google / outlook better than self-hosted for email server                                  prepaidgiftbalance
