[ale] MX Record Questions?

[Ryan Neily]

I have a question about backup MX records for e-mail. I have a server that
is a backup MX for another domain, and it is correctly receiving e-mail
for that domain, and storing it in the /var/spool/mqueue directoy untill
the primary MX comes back up. What I am confused about is that when people
e-mail someone at the domain while the primary MX is down, they get an
return e-mail from their sendmail server wth a suject "Warning: could not
send message for past 4 hours".

Since the e-mail has been received (by the backup MX at least) is there 
any way to make it so that the e-mailing users sendmail server does not 
send this e-mail out?  It's confusing for Joe Schmoe user to get these 
e-mails, and it seems a little redundant. 

Thanks in advance...
