[Dovecot] forbid some users and machines ?

2009-12-07 Thread Frank Bonnet 

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.
