Struct SecurityConfig 

pub struct SecurityConfig {
    pub relay_networks: Vec<String>,
    pub blocked_ips: Vec<String>,
    pub check_recipient_exists: bool,
    pub reject_unknown_recipients: bool,
}

Inbound relay and IP-filtering security configuration.

Fields

relay_networks: Vec<String>

Required. List of CIDR network ranges whose senders are allowed to relay mail through this server without authentication (e.g. ["127.0.0.0/8", "10.0.0.0/8"]).

blocked_ips: Vec<String>

Required. List of IP addresses that are unconditionally blocked from connecting. Both IPv4 and IPv6 addresses are accepted.

check_recipient_exists: bool

Required. When true, incoming mail is checked to verify the recipient mailbox exists before accepting the message.

reject_unknown_recipients: bool

Required. When true, connections from senders whose reverse DNS lookup fails or does not match are rejected.
