Taking down an Exchange server in a WAN Environment

I am planning some server maintenance in my Exchange 2000 environment
and plan on taking down a remote mail server for a few hours. Can
someone tell me what will happen to the mail directed at users who's
store resides on that server during that down time? Will it be lost, or
will it be cached until the server comes back up again?

Thanks for any help anyone can offer,

By default SMTP servers make several delivery attempts at different
intervals before sending out a Delivery Status Notification saying the
message will be delayed. Once the retry period - during which the server
keeps trying to send the message - expires, senders get a non-delivery
report (NDR).

Check your sending server's SMTP virtual server properties | Delivery tab |
Outbound section. This retry interval is specified in the "Expiration
timeout" field, and is 2 days by default. Delay notification is 12 hours by
default.
