Exchange server will not drop messages do to their age. This is not
something it is designed to do.
Is there a firwall or E-mail scanning software installed between you and
the Internet.
The reason I ask is if the ISP dropped 1800 messages on your environment
all at one time, it is possible that third-party software might not have
been able to handle the load and started rejecting messages.
Exchange will take any and all messages passed on to it regardless of time
stamp and amount. It might slow performance but it will not reject
messages.
Remember Outlook and Exchange have a feature that makes it possible to send
Delayed messages if a user desires to do so. So Exchange should not be an
issue.

I would look at the firewall logs, E-mail scanning logs and\or AV logs for
possible dropped connections.
