Description

When I use Outlook2016 (with wrong password) to connect a "mail proxy" type SSL port(465/993/995), always get 0x800CCC0F error.But it's ok when using "stream proxy".
After some research,I got a "I don't know how but it works" solution:

Edit mail/ngx_mail_handler.c:
1.copy void ngx_mail_close_connection to "ngx_mail_close_connection_keep"

2.remove "ngx_close_connection(c);" from void ngx_close_connection(c);
3.edit void ngx_mail_send change line 674 to ngx_mail_close_connection_keep(c);

        if (s->quit) {
            ngx_mail_close_connection_keep(c);
            return;
        }

Add "void ngx_mail_close_connection_keep(ngx_connection_t *c);" to mail/ngx_mail.h

=============
I don't know how it works, also don't know dos it has side effects,so I hope the connect issue can be fixed official.
