Well, I went to their link for requesting removal of blocked status but apparently we are not listed in any of their blacklists. They provide links to check your IP address and it comes up OK.

Our CEO is getting this message when trying to send an email to an individual who uses Road Runner. &nbsp;I followed the tenet instructions on another post here and I got an error when I did &quot;rcpt to: testaddress@nyc.rr.com&quot;. I got &quot;550 #5.1.0 arress rejected.&quot; I tried a valid email address as well and got the same error. When I look at the outbound queue in Exchange Manager I see a blue check mark for that domain as well as one for Sprintpcs.com. I have an SPF record in place, reverse dns works, althougth the name of the Exchange Server shows up as Barracuda(which I installed about a month ago) with it's associated IP address instead of the name and IP of our Exchange Server. Any direction would be greatly appreciated. It's difficult explaining anything to our CEO.

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
