Now a days, I'd get the boss to signup for Google Business Apps, configure DNS and be done with it. I've always been a huge fan of the gmail interface; the ease of config and maintenance and Gmail (rarely) goes down.

But - the boss doesn't want to do that.

I've tinkered with sendmail and and the lot of linux email systems over the years and the same has always been true; their incredibly difficult to configure, maintain and support. Email is generally pretty important and if it's not done right; people get pissed.

So - it's 2016 - has anyone solved setting up your own email server that's feature rich, easy to configure and reliable?

Right now - we do a ridiculous (setup well before me) dance with Mailgun where mailgun handles emails going to ourdomain.com and re-routes them to individual gmail accounts and the trip back is handled with an email alias and it's... just wrong. Coupled with yesterday we sent our monthly newsletter to 300k users (via mailgun) and we just found out almost half of them bounced and they bounced because "if the mailgun server your dedicated ip address is on fails in anyway, email fails over to another ip (owned by mailgun) and sent from there - unfortunately, this failover IP is on every spam list known to IT and the failover emails bounced."

Any opinions?
