Strangeness in 95/98 machine and qmail

[Bill Parker]

Hello all,

        I am writing in the hope someone can give me a clue as to what
might have happened.  I have a machine in our office which has a 
real ip address ending in .214 (it used to end in .249)...Now, ever since
it was changed, outlook express (the MTA the guy uses) has been barfing
sending and receiving mail outside of our domain.  Does anyone know why
this would happen, since I am not aware of anything in qmail which would
trigger this problem just by changing an IP address...
