How do I send an ID command (IMAP) in the mail module?

[Naresh V]

Hi,

As per my understanding of the mail module so far, the only
communication that is done with the upstream and then handled is the
LOGIN command in
http://lxr.evanmiller.org/http/source/mail/ngx_mail_proxy_module.c#L327
i.e.

nginx:C> a012 LOGIN user at domain password
dovecot:S> * OK

and then subsequent communication happens without any specific
handling by nginx.

I want to send a ID command <http://www.faqs.org/rfcs/rfc2971.html>
before the above LOGIN command, how do I go about it?

nginx:C> a012 ID ( "X-ORIGINATING-IP" "172.31.1.76" )
dovecot:S> * ID NIL
nginx:C> a012 LOGIN user at domain password
dovecot:S> * OK
