            Bug ID: 2596
           Summary: Changing the default value for the hosts_noproxy_tls
                    option breaks the use of smtp authorization
           Product: Exim
           Version: 4.93
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Transports
          Assignee: unallocated@???
          Reporter: prospero_ne@???

When using Exim as MTA for sending mail through an external smtp, while sending
emails from different users of the same smtp server, the hosts_noproxy_tls
option in the unset value allows you to send mail without authorization to an
existing smtp session.

Since version 4.93 the default value of the option has been changed:

JH/21 The smtp transport option "hosts_noproxy_tls" is now unset by default.
      A single TCP connection by a client will now hold a TLS connection open
     for multiple message deliveries, by default.  Previoud the default was to
     not do so.


This breaks the logic of work using multi-user smtp authorization.
