By 'clients' do you mean:
- user's who cannot type consistently or have set their MUA correctly
- *former* user's whose MUA have not had their old accounts
disabled/removed.
- apparent break-in attempts
And in any case, on which arrival port(s) and with which protocol?
The problem should go away with no need to blacklist if you get the
combination set optimally.
