Unable to Recieve Emails from Hotmail on hosted exchange

Hello all,

I have a bit of a problem. I have goggled around and found some answers but nothing that has worked. The problem is I have just switch my email over to office 365. At first we had no problems but then all of a sudden this week we were unable to receive emails from hotmail.com. I have check the DNS and made sure that the SPF and MX records are correct. The email doesn’t leave Hotmail server since there is no record of it on Forefront and the header also makes no mention of office 365 servers. Here is the header from the email:
x-store-info:D6taffyBScEUZsL+ZXbbDoZx0yi5SZysZfXspBzGGNxOTO3zOFVFvQLyrpoEPC/kh3/fYVW8Clh2OBy1FoLVmKlfmBgf0F/7wC4f1ij8jH/68POJUJJLwE+yPj8ZiVRPRsvvYQEOosE=

I have tried this on several Hotmail accounts all with the same result. One thing is if I reply to an email that I send to Hotmail it goes through with no problem. It is just a new mail message. There is no problems sending and receiving to other domains just Hotmail. I also have set up a policy in Forefront to allow all email from Hotmail.

One thing is we have a web site that is hosted on a different IP. We have an "a record" pointing to that. I have read that Hotmail is delivering emails based off an "a record" then that could be the only thing I can think of. How could I work around that?

Thanks,
Brian

Checked your ip address blacklist or not if it's blacklist then contact ISP to convert it whitelist becuase some time blacklist ip address also block the mails.

unable to relay means it is being blocked by policy.  What filtering have you got in place between your server and hotmail?

I have checked the blacklist and we are not on any of them.
We have no policies on my end. How do I check if hotmail has any?

almost every transmission of email has some policy applied to it these days.  I would be very surprised if you had nothing at all.  At the very basic level Microsoft SMTP service has relay prevention policies allowing only some computers to relay.  Then you have your firewall, ISP, intelligent message filtering, reverse DNS and sender verify... those last two are built into exhcange server so exist by default although turned off.

If you domain name and ip address is in whitelisted then Hotmail not set any policies.

Please check your domain name also is it blacklist or not???

@CPG
How would I check that then. I have not configured anything on the exchange server but to allow all hotmail.com email through.  
@sushiil84
I just did a check of the IP and of the domain name both came back good.

shouldn't be necessary to manually allow hotmail.com traffic.

are you always testing using the same recipient at the other end?  unable to relay can sometimes mean the recipient has reached their mailbox limit.  Did you already try sending to another user?

I understand that I shouldnt have to manully allow hotmail.com traffic but I was despart so that why I did that.

I have tried to send to almost everyone in my office (using 4 differnt hotmail accounts) with the same results. Able to reply to an email but unable to send a new email.

If i am correct, you are using FOPE - online protection version of Forefront.

My best bet is hotmail is querying something weird and is unable to get through, also understand Forefront has built in connectors for certain of its users, which does not get updated with new MX Records.

Open a ticket with FOPE team and ask them to investigate on this issue.

This has nothing to do with you cause hotmail has to relay through FOPE to send to you, assuming (kick me hard if i am wrong) that you are getting emails from other domains correctly - this is a MS issue.

Just got off the phone with Microsoft support and they told that he can not see any emails comming in from there server on the headers that there is nothing he can do. He asked me to get in connact with Hotmail support. Waiting for them to get back to me.
I did change my SPF record from the one that Microsoft says to use to a custom one that says all ip address in my domain can send email. That seems to have made a differnce. Will wait and see if the problems reoccurs.

Exchange_GeekCommented:
Type the SPF Record that you've made changes to.

I think MS guy has gone crazy if he is not allowing the SPF to me limited to a set of IPs or MX or PTR or all of the above.

I'm eager to read your response.

Exchange_Geek

Still waiting for the Hotmail guy to get back to me. I will post the SPF record a little later today.

Sorry for the delay. It seems the SRF record did the trick. I am awarding Exchange_Geek because his answer got me going in the correct direction.
Here is the SRF record v=spf1 a mx:xxx-com.mail.eo.outlook.com include:outlook.com ?all
Thanks to all for your help
