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

Actually there is a great tool for that, grepcidr $ echo 10.11.12.127 | grepcidr 10.11.12.0/25 && echo OK 10.11.12.127 OK $ echo 10.11.12.128 | grepcidr 10.11.12.0/25 && echo OK $ But in your case you really probably should use postgres for the userdb and just return everything from there in user fields / extra fields, and if the...

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. https://wiki.dovecot.org/PostLoginScripting I have implemented this myself on a small open source project, I can send you the links of you want.
