SMTP error status 5.3.5 Email looping. Using Gmail

I have a problem with SMTP configuration.

I use Gmail with my domain for ex. www.mydomain.com. When I try to send email from server under that domain to [email protected] I get fail report

Final-Recipient: rfc822;[email protected]
Action: failed
Status: 5.3.5

MX records are as in Google configuration wizard. Why is the mail looping? 

10 alt2.aspmx.l.google.com  
10 aspmx.l.google.com.mydomain.com  
10 alt1.aspmx.l.google.com  
20 aspmx2.googlemail.com    
20 aspmx3.googlemail.com

My server is IIS 7, with default SMTP service.

Thank you for any help.

If someone will find this question, problem was with DNS MX records:

aspmx.l.google.com.mydomain.com

but it should be 

aspmx.l.google.com

Apparently this was causing the loop.
