[Feature Request] Support RFC2971, IMAP ID extension.

[Catty2014]

Is your feature request related to a problem? Please describe.

I attempted to connect Nextcloud Mail with my Netease Mail(163.com), however it gets hung at inbox page, like #10219. Information "Unsafe Login. Please contact [email protected] for help" is in the debug log.

Describe the solution you'd like

According to this page, RFC2917(IMAP ID Extension) should be used to communicate with server. Thus I'd expect Nextcloud Mail to support IMAP ID.

Describe alternatives you've considered

No response

Additional context

I'd like to inspect if horde-imap_client supports IMAP ID or relevant.

Thanks for your feature request 👍

Horde does support the RFC 2971 / IMAP4 ID extension.

You can try patching your instance like that and see if it's already enough. My understanding of 2917 is that a client may send an ID, but a server should not require it.
