You should find an entry in your /var/log/maillog bouncing the
message back to the sender ..

or at command-line issue this:

cat /var/log/maillog | grep "MAILER-DAEMON"

and see the output.

The reason I said it was the SMTP server of the sender is
because some SMTP has a limitation of size of message
that can go through and end-users within the network
only see the bounced message and think it was rejected
from the Recipent Server (your server).

Since your user can send you the bounce error message
ask her to quote the full header of the message which will
show clearly if it was rejected by the Internal Exchange
Server or by your Server.

Plus the text format of the bounce message looks
like an exchange server SMTP error message.
