The DNS servers for blanca.ma are srv1-blanca.ma and 
srv2-blanca.ma.  srv2-blanca.ma is not returning an answer for 
queries about blanca.ma.  That behaviour is due to a 
misconfiguration.  Note that incorrect DNS configuration for a domain 
can affect mail delivery.

As for your gmail problem, it is not possible to determine why you 
cannot send mail from there without any technical 
information.  Usually, when a mail delivery fails, the sending mail 
server, in this case gmail, notifies the sender of the failure by 
sending a bounce message.  That message usually contains some 
technical information such as the transcript of the SMTP session to 
one of the MX servers for blanca.ma.  You can tell which MX server 
gmail attempted to deliver the message to and what SMTP error was 
returned by the blanca.ma mail server.

The first step is to fix the incorrect DNS configuration.  Then send 
a test message from gmail and read the bounce message if the mail 
delivery fails.  If you don't have a bounce message, you'll have to 
contact gmail about the mail delivery problem.
