Exchange 2010 bouncing back some emails from different providers to 3 users

I need some help with this, I have 3 users that when multiple users with different email providers send them emails they get this bounce back. not with all the outside users happens either. other Users inside my organization have no problem receiving from this users. i have checked their blocked senders list, spam folder and filter. I run this command from the power shell (Get-MailboxJunkEmailConfiguration username).blockedsendersanddomains and i see just one adress in one user not related with the bounce backs, the other two users have no emails blocked.

The response was:

550 permanent failure for one or more recipients (user@domain.com:blocked)

Final-Recipient: rfc822; user@domain.com .com
Action: failed
Status: 5.0.0
Remote-MTA: dns; d91072a.ess.barracudanetworks.com. (an IP the company does not have., the server
for the domain domain.com)
Diagnostic-Code: smtp; 550 permanent failure for one or more recipients user@domain.com:blocked)
