[comp.mail.sendmail] Reliablity: two machines with one name?

xiaoy@bullet.ecf (XIAO Yan) (05/24/91)

Don't know whether this is the most proper place to make this request.

If I give two machines the same name (with different IP address), will I
get more reliability in terms of mail function?

Right now whenever our major e-mail machine (call it A) is down, I make 
another machine (call it B) act like A by setting B's host_id to A's
and we don't seem to lose any mail.  

Is sendmail smart enough, or is it usually configured in a way, 
that if no response from A, then check some other machine(s)
(say B) with the same name as A?

  No.  You will finish up with a disaster.

  Learn about using nameservers and MX records.  They are the solution to
your problem.
