WHAT HAPPENS when you -try- to send an email _out_?  
    Do you get an error email?
    Does it show in the outbound mail queue?
       (if it's in the queue, look at the qf* file, to see why it is deferred.)

WHAT HAPPENS when  somebody -tries- to send an email _in_ from somewhere else?
    Do  they get an error email?
    Does it show in their outbound mail queue?
    What do your sendmail log messages say?

WHAT HAPPENS when you 'telnet' to your mailserver port(s) and try doing smtp
  transaction(s) manually?
