[ILUG] Searching for attachments in email

I posted this earlier from an other account might it have
gone for moderation?

HI All

    I need to search an excel document for the  word " brno"
the problem and the point where this relates to Linux is the
excel docs that need to be searched are in attachments
in users email accounts. The server is running courier-imap
on SUSE 9.3.

    What I think I need to do is find some way to find all files
created between two dates (I have a date range) and
have an attached excel file with the at lest one of the words
"over" or "held" in the file name then extract the attached
excel files and copy them to some place on my local PC
its running Ubunut 6.10.Then run an open office macro over
them to find the phrase I require

    How would one extract the excel files without going in via
the imap server as this would be tedious because of the amount
of email accounts on the box and the number of folders in each
account.

I have root on this box  and can ssh to it. Any Ideas.
