You could override the %u variable, but overriding it in userdb will
have surprising consequences. Basically this amounts to same as changing
username for the user. So don't. Please set some other thing like,
my_special_var=something in userdb, then you should be able to access it
as env.vnd.dovecot.my_special_var
