    Pregunta

  • Folks,

    I run SBS 2008 with Exchange 2007.  I'm getting a complaint from one outside person (using gmail.com) trying to send email to one of our employees.  Apparently sometimes the emails go through and sometimes he gets the bounce message below.  I looked to see if I was on any block lists and couldn't find any.  Any ideas how I can fix this?

    Thanks,

    Mike
