Emails sent to hotmail never received by recipient but recieve reply to

We have an Exchange 2007 environment, our ISP is actually what is called an ITC as we are a public school system. We ended up blacklisted for awhile due to a virus but after that was fixed all was well. Now, again we are having issues with Hotmail. We can reply to: any Hotmail message and it will be received. However, if we originate an email to a Hotmail address it goes into never-never land. Plus, there isn't any way that I can find to speak with technical support to fix this issue. There's a community forum but that's it. Any and all suggestions are appreciated.

At this point, we are not on a blacklist. Our domain is wilmington.k12.oh.us if you want to check also. In addition, I had our ITC add an SPF record for our mail server. Now, I'm pulling my hair out because it still isn't working.

I have also tried Telneting and it says the message is queued but is processed but our server. So, I'm guessing it is queued on their server.

How long ago did you add the SPF record? It can take upto 48 hours to populate.
Is it correct? Check by running this wizard: http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/

It can take 48 hours to populate to all DNS servers.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

It was yesterday but I'm not 100% sure the syntax is right. I've modified it and sent it to our ITC. They generated the first one but MX wasn't listed within the SPF record.

I've had the same issue... spf record intact, had to contact live technical support, they forwarded it to someone and we were back.

looking at your DNS, it appears that you're using mveca.mx.esu.k12.oh.us as a MX... is that where it's sent from?  If so you're listed: http://www.mxtoolbox.com/SuperTool.aspx?action=blacklist%3a208.108.11.226
with backscatter...

We ended up using our ITC as a SmartHost which seemed to resolve the issue. I'm not sure what the problem was but not being able to get a hold of anyone from Hotmail is really frustrating!
