Hello, A user has left and our central authentication (MS ADO via PAM/LDAP) his disabled his login so he cannot collect any incoming e-mail, however until they cancel (rather than disable) the account, the e-mail address is still valid. The accounts on the Linux system simply track those on MS ADO via scripts using LDAP etc.,., Is there a simple way a current account can be made inoperative so that mail to the account receives a no-such user response. [I'm also thinking about the possibility of a disgruntled former employee indulging in a quiet spot of mail bombing.]

If you're requiring SMTP authentication (and you should be) then he shouldn't be able to send email from his old address, the account should only be able to receive mail (since incoming SMTP only checks for an accounts existence, it doesn't try to authenticate). If you want to completely disable the account you'll need to modify whatever attribute Courier does email lookups against. Normally in LDAP this is the mail attribute so part of your account disable proces could be to change the ldap mail attribute to blank or disabled or whatever.
