And while my cost per user is closer to $1/user ( I think I'm paying $1.10/user), assuming I can solve the two issues listed in my other thread will push me to O365 when my current Open License SA expires.
It's amazing what already paying over 25% of the cost does to offset the equation!

No it's not included - that's an additional fee - or at least it was 10 years ago when we signed up. At this time I'm not sure what it would gain us by sending email out though them? again we've only been on a blacklist once in since 2001.
That's just crazy. I can't believe you've never faced blacklisting. It used to happen so capriciously.
I hear stories about this all the time. But I've not found it to be true. When I was a consultant supporting about 15 local companies, all of which hosted locally, blacklisting happened about once a year over all the clients.
I have my company and other other that I still support (that moved to RS 2 years ago) that until that point only one BL between them in 10+ years.

Sure, but my two issues are pretty large show stoppers for our business...

As almost all of our clients used to run SBS, all email was locally hosted. and 2 still are (one on SBS 2008, the other on Exchange 2010).
They have never been blacklisted because I have always blocked outbound port 25 on my networks for all devices except the email server itself.
Getting blacklisted requires allowing something to happen. It does not just capriciously happen.

Exactly - that is why I mentioned using a dedicated IP that the firewall only allows traffic from the mail server itself to use, then you don't have to worry about blacklisting... but Jared's method is equally as good too.

I've had customers long ago get blocked for being on a bad block, even though their address was not in question.
Blocking can be done by reporting, so competitors can get you blocked, or used to be able to.

Thanks any answers and explanation ... problem solved, after requesting to microsoft and re setting my send connector issue ..
1000 thumbs for this forum -
So glad that we were able to help and very glad to have you here!

how to mark this post to [solved] ..

That's not a functionality that we have here yet. But we might have it soon. It is being tested on some of the other forums.

Wait, are you saying that anyone who runs on-premise e-mail is an idiot?
I have been blacklisted in the past, when I was younger and naive, but I reckon configuring the firewall to only allow the mail server to use port 25 solves 99% of problems. If people you know are constantly getting blacklisted than I suggest they've got much bigger problems than simply using on-premise e-mail. It's like saying "my house keeps burning down so I've decided to move to a fire-proof house".
I've never heard of competitors being able to block your IP address by simply reporting it. That sounds a bit dodgy.

Blacklists are not big companies, are all individual and can do whatever they want. Some of them accept reports, or used to, as to spam. If you think about it, how does anyone determine that something is a spam relay? The blacklists have to get that information from somewhere.

That's not what I said. If you read the lead in to the list, I pointed out that these things were things that typically or generally happened with on premises systems. So "anyone" doesn't apply here. And not being an email specialist is in no way the same thing as an idiot, so the idiot bit does not apply.
What I was pointing out is that because by and large the vast majority of email systems should be hosted but many are not there is a very high incidence of people lacking deep email experience that, partially due to that very lack of knowledge and experience, decide to run email in house and/or lack the wherewithal to convince the powers that be that hosted email is needed. This creates a situation where there is a higher chance that on premises email systems are being run by people who don't have a lot of email experience or knowledge - it's self fulfilling in that way. People with the most email experience and knowledge are the most likely to be pushing for email to be hosted (talking averages here, not specific cases) and will also have the most clout to convince management to do so.

Most of them have email addresses setup to get spam and if they receive on the address, it is added to the database and blacklisted once some threshhold is met.

Many do, sure. But at least in the 2000s, it was very common for blacklists to accept reports on IP addresses and block based on that.

A quick search and SpamCop accepts end user submissions. I found some sites listing tons of services for submissions (dozen or so, if that is tons) suggesting that they all accepted end user submission. Only takes a few of the common ones to be an issue for someone if someone starts submitting them.

submissions of what?
"Hey block this IP because I say it is bad?" or "hey here is a copy of a spam email to add to your algorithm."Significantly different.

Why is it different? Since you can craft the email to submit or modify it however you want, you are literally submitting an IP address manually.
While the submission process is complex and you need an example, none of it is even remotely difficult to use as a pure IP address submission. Use any SPAM email or craft one, put in the IP source that you want blocked and submit.

Because the first is you simply taking my word for it and blocking an IP. The second is adding a (possibly faked email) to an existing database of emails that does not just block for a single thing. it uses an algorithm to set the scores.

But not for the IP address right? Presumably we all have an endless supply of spam. yes that is an assumption but I'm confident that this is reasonably true. Given that we have an endless supply of example spam to work with, the IP address portion is and always has been "taking their word for it" in cases of submissions. Am I missing some component here where I don't just choose the IP address to submit (if I want to?)
