I think the best way would be to modify the qmailadmin source and execute the relevant C API to FileMaker (if it exists), or I can use an existing PHP API to FileMaker to update password changes. This would mean an execl("php /www/data/update.php") command.
Take a look at "README.hooks" in the QmailAdmin 1.2 source directory. It explains how to have QmailAdmin execute external commands when adding/modifying/deleting users.
