Block IP with mailboxd

[tdslot]

Hello to All,

I have question. It is possible block some IP or subnet with mailboxd ? Like add in configuration IP or networks.

Problem is that mail server is behind firewall and firewall do NAT and port forward. I do not control firewall. And from internet is always going scan via IMAP service users. They try check user name and user password. It was couple times that they phished password and did SPAM attack over my server.

I checked this https://wiki.zimbra.com/wiki/DoSFilter but it seems that it do some thing different what I need.

Thank you in advance.
