[ale] dialup and sendmail

[andy]

I had a similar problem but i did not modify sendmail.cf
I am using Red Hat 5.1 and am currently stuck with dynamic
address until the move to cable.  What I did was just changed
my machine name to one of the dynamic ones used by my isp.
and now i can send mail anywhere, but obviously  i still can't receive
mail unless my snagged machine name matches the one that's
assigned at dialup.
