My only issue with this is that there is no guarantee you will get all the
email as there is no way to guarantee the sending servers will keep
retrying.
That's why I have 2 gateways. One is offsite.

I don't think you will lose mail. The senders will keep their messages in
their own queues while you are fixing your relay. Once your relay is up,
messages will come in.

Exchange 5.5
Windows NT 4 sp6
�
We have a mail relay that sits on our only other server with an external
connection which relays mail to our exchange server.
�
I have recently changed our exchange server to only accept connections from
our internal/external subnets.� This reduced most of our spam which turns
out was coming directly to our exchange server which is why antispam
measures on the relay were not accomplishing much.� Since I have done this,
most of our spam is gone, with a little bit slipping through on the relay.
�
Someone just brought up here that if our relay went down, it used to be that
mail could still come through because it would go directly to our exchange
server, and that with the changes I have made, our mail would stop.
�
I do not feel opening the exchange server back to accepting outside
connections is the right thing to do.� However, my boss does not want to
purchase another machine, and as I said our relay is the only other machine
with an outside connection.� 
�
Anyone have any thoughts on the best solution to prevent the loss of email
if our relay server were to crash.
�
Thanks.�
