Hello, Zhang.
You can easily do this without a new feature in Dovecot.
- Create a post login script, for instance, in bash.
- install grepcidr on your server.
Your post login script can use grepcidr to check for white or black list.

I have implemented this myself on a small open source project, I can send you the links of you want.
André.

Dear all,
We use
allow_nets[1] to restrict login clients, it works fine. Recently we need to allow some users to login from everywhere except some IP/networks, how can we accomplish this with "allow_nets"?Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid network '!a.b.c.d'".
Can we have this feature?
i guess it should be done in function "auth_request_validate_networks"[2] in file src/auth/auth-request.c.
