After examining the mail folders closer, i've concluded that it is not something in the updateLDAPValues_072_to_073.py.
Instead of storing mail in /var/vmail, all new mail since the upgrade has been stored in /var/vmail/vmail.
I also ran
at the same time with the following results in the log:

So, it is possible that one of these may have caused the change to the path of the mail.
Additionally, here is the storage attributes for one user whose mail is no longer visible:
homeDirectory: /var/vmail/domain.com/w/we/web/web-2010.08.17.07.54.26/
mailMessageStore: vmail/domain.com/w/we/web/web-2010.08.17.07.54.26/
storageBaseDirectory: /var
Also just for S&Gs, here is the line of my dovecot-ldap.conf file that sets the maildir:
user_attrs = homeDirectory=home,mailMessageStore=mail=maildir:/var/vmail/%$/Maildir/,mailQuota=quota_rule=*:bytes=%$
Note that this conf file has not been updated in several months:
