dovecot - Dec 2009 - forbid some users and machines ?

Hello

1 - Is there a way to forbid log in of some Dovecot's users ?
     I use NIS as authentication mechanism.

2 - Is it possible to forbid some machines (IP addresses ) to
     connect to Dovecot server ?

Thank you

Yes, with Linux you can use iptables.

http://wiki.dovecot.org/Authentication/RestrictAccess

add this before any other passdb & read the Variables page about %Ls (You 
probably don't need it)

passdb passwd-file {
   args = /etc/dovecot/deny.%Ls
   deny = yes
}

Besides the iptables (or similiar on other OSs) approach, there is 
"Restricting IP Access" on the same page. Though, I don't know
since when
this feature is available.
