Struct ImapSessionOpenOptions 

pub struct ImapSessionOpenOptions {
    pub starttls: bool,
    pub auto_id: Option<Vec<(IString<'static>, NString<'static>)>>,
    pub sasl_ir: Option<bool>,
}

Provider-quirk and policy options for ImapSessionOpen::new.

The default upgrades nothing, sends no ID and follows the server’s advertised capabilities.

Fields

starttls: bool

Whether to upgrade the connection with STARTTLS after the greeting. Only valid on a cleartext transport, since ImapSessionTransport::Tls is already encrypted.

auto_id: Option<Vec<(IString<'static>, NString<'static>)>>

ID parameters consumed by the authentication step, required by a few providers (mail.qq.com, Fastmail).

None skips, Some(empty) sends ID NIL, Some(params) sends ID (k v ...).

sasl_ir: Option<bool>

Forces the RFC 4959 SASL-IR initial response on or off.

Some(true) inlines it with the AUTHENTICATE command, Some(false) waits for the server’s continuation request, and None follows the advertised SASL-IR capability. Coremail (126.com, 163.com) advertises it falsely, and no capability inspection can predict that.
