I don't get mails from outlook.com

[rscheihi]

Hi,

Since some time ago I'm not receiving e-mails sent from outlook.com.
The problems seems to be with my domain, because no one in my domain
receives e-mails from outlook.
I created an account in outlook to make tests, but I don't get much information.
Looking in the maillog (in my server), there is no trace of e-mails coming from outlook, and outlook.com doesn't give any info about the communication between the MTAs.

Any idea?

Thanks,

Rodrigo.
