Email all Pilots

Hi I wonder if anyone can help. When I try to email from my admin center it all looks fine but the mail does not go. Instead I get an email saying Mail failure - rejected by local scanning code

A message that you sent was rejected by the local scanning code that
checks incoming messages on this system. The following error was given:

  Local sendmail disabled

 

My webmail works fine and other VA’s mass email work ok so its not a hosting problem.

 

Can anyone help

 

Thanks
