Hi, Inbound mail to a specific user is been forwarded to his external mailbox at another domain. Add mails are routed correctly with the exception of one domain. When mail are sent to users of my domain, including that user, the mails are delivered to everyone except him...as the mail admin I am getting the message

The following recipient(s) cannot be reached:
  usermailbox on 1/10/2011 1:27 PM
        There was a SMTP communication problem with the
recipient's email server. Please contact your system administrator. email.speedimpex.com #5.5.0 smtp;587 [email protected] sender domain does not match SPF records>

I am sure this has nothing to do with my mail server, however, can someone confirm?

Office365 SPF record has too many lookups

as seen on Server Fault - Search for 'Server Fault'
For some utterly ridiculous administrative reasons we've got a split domain with one mailbox on Office365 which requires us to add include:outlook.com to our SPF record. The problem with this is that that rule alone requires nine DNS lookups of the maximum of 10. Seriously, it's horrible. Just look… >>> More
