Question : Exchange 2007 error 550

We have purchased a secondary domain gsleneryllc.com it is being hosted by GoDaddy.  Our primary domain gslelectric.com is hosted by network solutions.  I have the mx record for GSLEnergyllc.com pointing to mail.gslelectric.com which is the main MX record for the company.  When I try to send an email to an email address on gslenergyllc.com from the inside our exchange environment it does work.  The barracuda does see the email coming in and it claims it has delivered the email.  From the GSLenergyllc.com we can also send email both internally and externally.

Answer : Exchange 2007 error 550

you would need to configure your exchange to allow the emails for the second domain.

Take help from the article below:
