          Here is the setup.  We are on a private vlan as in 192.168.x.x.
All local host names are resolved via hosts files.  Messages to
go to the big wide world must go through Suddenlink's SMTP
smarthost and I definitely don't want to break that.
	On rare occasions, I want to forward an email to the Mac
which normally doesn't send or receive emails.  What would be the
simplest way to "forward" an email from the Linux box to the
Mac's mailer?
	The Mac only needs to be able to receive, not send any
email.
Thank you

        Why not create a user on the Linux box to receive such emails
          and have the MAC client connect to that user on the Linux
          box.  You might have to install a pop server (popa3d ...
          easiest to install and configure) or imac server
          (dovecot-imapd ... harder to configure and probably more than
          you need) on the Linux box if one isn't installed already.  
        
        Your MAC would have to have an email client capable of
          connecting to a pop or imac mailbox at the ip of the Linux box
          or host name in the hosts file corresponding to the Linux box.
        
      
      
      
      Hi Martin,
      
      
      
      The setup Bob describes is exactly what I use for my family.
         Debian linux box running dovecot receives email from our ISP
        via "fetchmail" and sorts it out to separate accounts for each
        family member, who then reads their mail on a Mac or PC using
        the native OS gui mail-reader on their machine.
      
      
      
      Feel free to ask me if you have any questions.
      
    
    Why doesn't each user use the native reader to get the mail from
      the ISP? What is the reason for the extra step? 
    
    I've never been able to quite figure out where I would need
      fetchmail in my mail setup but every howto seems to mention it, so
      I am curious to see if I am missing something.
