[comp.mail.sendmail] PROBLEM: sendmail on Apollo -- some machines unreachable

chris@asylum.gsfc.nasa.gov (Chris Shenton) (08/31/90)

I'm having problems getting to quite a number of sites, especially those in
the .COM domain; I don't seem to have problems getting to .EDU or .GOV
machines. An example (names changed to protect the innocent :-):

I want to send to foo@hostname.Company.COM, but the message gets defferred
with a timeout, and eventually gets bounced back to me after three days.  I
can get it there if I send it to foo@Company.COM (presumably a mailserver
at Company), **or** by sending to foo@hostname.Company.COM@uunet.UU.NET.
What's the deal?

The nameserver here at gsfc.nasa.gov tells me the ip address of both
hostnames, so that shouldn't be a problem. Is it a broken sendmail.cf? or
is my mail software brain-damaged.

Any enlightenment you'd care to pass on is greatly appreciated (in advance!)
