Shyb -
is your public IP static or dynamic ??

That message means that your IP address has been blocked by a Black List (FBLW15, the BL in that is certainly representing the words Black List.) It is just a list of IPs that are blocked. If you are hosting your own email outside of a datacenter, this is quite common and will likely recur regularly.
The error message tells you the only course of action, you need to email [email protected] and request to be taken off of the list.

cuz if his email server on premise and have a dynamic public IP your sending email will be considered as spam and will be rejected by other email servers

It is important to understand what has happened here. There is no technical problem, this is a policy problem. Microsoft (in this case) has decided for some reason (which could be as simple as not having had a PTR record, running on a dynamic IP, using an IP that was an issue before, having been an open relay, false reporting, etc.) that you are a spam host and your IP address has been black listed. Plain and simple. They have themselves decided to not accept email from you. Your system is working fine, they are refusing delivery. That's their decision and there is nothing you can do about it except beg them to change that decision. Emailing them and hoping for the best is literally your only course of action without moving to hosted email.
I assume you are not in the US and have different costs, reliability concerns, etc. but one of the most key reasons for email to never be run on premises for American companies is because when you decide to host your own email, as you are here, that means that you have decided to have problems like this. Only the biggest hosts like Office 365, Rackspace and Gmail have the clout and power to make sure that they are never blacklisted. You always use these when email delivery reliability matters. If you run email on premises without being fronted by an enterprise email host or go completely hosted, you have accepted that email delivery will not be reliable.
This is simply the accepted artifact of running your own email server - which should effectively never happen for business email. It's just not something that companies should be doing. It is too costly and too risky.

He is having technical issues and cannot respond at the moment.

I think Scott is over selling this here - but then again he's a complete fan of hosted email.
While Blacklisting can and does happen to those that are self hosted - it's really not that common unless you have other issues - like someone on your network starts sending our spam on the same IP that your email server is registered for, or you're using a dymanic IP with no PTR as Scott mentioned.If possible get yourself a static IP that is ONLY used for email and most of those problems will go away.

Like hosting your own email server

The problems with self hosting are cumulative. I know of no one hosting their own email system that isn't regularly hit with blacklists. Of course, I've dealt with no business willing to do this in over a decade, the issues were so intense that the idea has finally fizzled out and no longer exists in the business world in the west. Those that want the "feel" of self hosting email do so by running Exchange in house but having a mailbagger running in the hosted space as the real email server (MXLogic, Postini and similar services.) They are the actual email servers and so the email is hosted, the mailboxes are the only part that are local (which are post-email services, excuse the pun.)
When you self host you are dealing with lots of issues that while not absolutely necessary, generally occur:
- Lack of knowledge of email systems (or else they would be hosted) leading to more issues below
- Lack of PTR and other important security records that need understood and maintained
- Lack of patching, system updates and other issues that can lead to being out of date with standards (or breaches)
- Dynamic IP addresses or using address pools that are blacklisted. Entire ISPs are blacklisted so this is very possible.
- Being in a country that is often blacklisted! Very little to be done about that one.
- Bad user behaviour.
- Malicious competitors who report you and get you blacklisted. This isn't always a technical issue.
- Accidentally having an open relay either on your email server or possibly even on another server.

Yes, we've found it to be very nice for having quick, effective conversations. It's so easy to respond quickly and see what other people are doing. Other sites I have found the same conversation can take all day that only takes a few minutes here. You can bring up the response windows quickly, type quickly, no site delays. And other people see what you post almost instantly.
At other sites it takes me easily ten times as long to post a response and then since I never see anyone else respond I have to wait for an email to come to me to tell me that someone responded and often that takes 30 minutes or so from the time that they post something until the email sends! So getting help on other systems can take forever. Here it is like a flowing conversation.

Here is a tool that you should be using regularly:
http://mxtoolbox.com/blacklists.aspx
Put in your email server details there and it will check the major blacklists to see who is blacklisting you. When your email is healthy, no one should be blacklisting you.

My employer has been hosting their own email since 1999, when they got email. I took over support of those system in 2001. Since that time they've been on a black list exactly one time.
Maybe you can count me as someone you know now?

You send directly from your own email system and don't have a front end hosted somewhere like Postini or MXLogic?

Yes I send direct from my own machine and No I don't have a front end like Postini. But I do use AppRiver to receive all of my email to filter out spam and virus...

Your SMTP doesn't connect to AppRiver? Isn't that included in the service?

wht is AppRiver ??

AppRiver is a competitor with MXLogic and Postini. They have a nice service. They handle sending and receiving your email so that your Exchange server does not need to talk to others directly. When they receive email they handle spam filtering and antivirus so that you do not have to. And they receive email and store it for you even if you are not online.
They can also handle sending email for you. So you send to them and then they send to others so that they handle making sure that they are not blacklisted.
