Re: 'connection refused' for the "double-bounce" address, but mail's delivered?

Sry, talking to myself a bunch :-/

I changed

        main.cf

        -       address_verify_transport_maps = 
static:vpn:[back.mail01.example.com]:25
        +       address_verify_transport_maps =

        master.cf

                [mail01.example.com]:25 inet n - n - 1 postscreen
                 -o smtpd_service_name=psint

                psint pass - - n - - smtpd
        +         -o 
address_verify_transport_maps=static:vpn:[back.mail01.example.com]:25
                  ...

and to initial test that seems to be working for address verification only at 
the postscreen instance.  And no errors I can see.

Yet.

Now to wait for something to trigger one of those double-bounce messages.
