Somebody who heard I was looking into an email server was wondering why I wouldn't just use my host's email server. Well, DigitalOcean doesn't even have one! Why not?!
Use g-suite. For $5 a month you get the whole g-suite including mail, drive and calendars. I went through this last year and it good.
I happen to use all of those things for FREE anyway on my personal gmail account...
If you use all of those things for free (including mail) then why are you trying to setup a droplet server to handle that?
I'm using the droplet anyway for my web development and business attempt. The $5 is the minimum I could get to have a reliable server with nodejs support.
No, and no.
But what's the difference? Nothing! That's precisely the problem. You (and google, to be fair) want me to pay $5/month to label my google account with my new email. Uh uh uh...
Eh? How do you mean? I don't think you're right in this case. By the way use reply on my comment, don't make a new answer every time.
