Not very practical on premise... there is not enough space in this thread to say how impractical it is on premise. The only thing we would lose is the relay, with copiers doing a send to email. Having Exchange hosted, we've found supporting articles and I believe a couple MS engineers, saying we would have significant issues so we steered away from that.
Relays are trivial. That's not a reason to not go hosted. If you really need a relay, that's a tiny project on Linux.

I'm not against switching by any means. Especially to Zimbra. But they can't bash something like that without providing an alternative. That's just ignorant.
I don't know that I agree. Knowing that something doesn't work well doesn't require knowing what does work well.
Someone can drive cars and drive one that they hate and know that there are cars that they like without knowing model names.

So I'm reading Facebook and laughing that this girl I know is screaming because a squirrel got chased into her house and is hiding behind the bed. Ha ha....
Oh wait, that's the girl that lives in my house. Doh!

But they should at least have something to compare it to if they are suggesting we switch to something else. Haha this person is so incredibly rude 100% of the time, I am not giving them the benefit of the doubt on ANY level.

How does that work...? I'm trying to think of the steps.

You do a generic install, CentOS 7 Minimal, for example. You open port 25 to the LAN and you set the Postfix settings to allow local relay. That's it. Nothing to install. One firewall port to open. One config line to change. Done.
-
That's for generic relay, if you want authenticated relay, you can do more config steps and make Postfix sign into O365 or Gmail or whatever.

So then when you scan to email from the copier... it's going to look on the local LAN for 25, find the Linux relay, the relay points to the hosted instance of Exchange...?

I can see how the Linux relay could point to O365, I'm having difficulty seeing how a copier would point to the Linux relay. Like if you had 2 copiers, and 2 different relays (maybe not practical, just seeing how you could have a copier be pointed at that specific relay).

It works the same as it does now. Which is it looks to the server and the server relays the message on. Nothing changes at all in how it works. Just Postfix instead of Exchange.

Well, HOW do you point it to your relay now? Nothing would change there. And using two relays, while REALLY weird, is super simple.

Ok, so the copier is seeing the Postfix server instead of Exchange, but then Postfix just forwards it on to the hosted Exchange instance?

Postfix sends it to whatever email address it's told to send to. That's what Exchange is doing now.

There's an option in our Konicas that you to put in the server's FQDN. I guess you could just enter that Linux server in there...

Sure.
But you said that you have a relay now. How is that working? How is the copier finding the Exchange server today?

Pretty janky actually. We have an older 2007 Exchange server, and a newer 2013 Exchange server. Old server has receive relay from a variety of IPs (copiers are included), then forwards off to the newer Exchange server if the message has to continue on. Hoping we get enough money and time this summer to dump the old instance, stand up a second 2013 instance and configure a DAG for balance/failover. Would be nice to have 2 servers on the same version.
Edit: It's more of a time matter, we've already had the funding set aside for a while since it doesn't cost that much.
-
But that doesn't explain how the copiers POINT to the Exchange 2007 instance. How do they send the email to it in the first place? IP address?
-
Why not replace that old Exchange machine with Postfix today? What's the purpose for keeping something old like that around?

Uses the hostname instead of IP... Some of the settings I've saw in the config:
Server FQDN: exchange-server.domain.com (older server with relay configured)
Server Port: 25
From Address: [email protected] (has a resource mailbox in Exchange, with a password to authenticate)I can't think of any other settings off the top of my head...

It's more time than cost.. The CALs aren't expensive. It's definitely not sticking around for functionality. We are stretched pretty thin so we have enough time to do about 10 users per month. Some users have like 50GB mailboxes so trying to migrate them runs for a long time then fails everyone after them. So we identify the larger mailboxes and run those on their own. I've increased the sizes on the new databases to unlimited for the transfer size (I think they were defaulted to about 2GB) and all of them pass fine except ones that are over about 10-20GB.
