DSN only for SASL-Authenticated users ?

[Marek Salwerowicz]

Hi list,

I have disabled globally DSN in my  main.cf:
smtpd_discard_ehlo_keyword_address_maps = cidr:/etc/postfix/dsn_access
/etc/postfix/dsn_access:

# block folllowing
0.0.0.0/0           silent-discard, dsn
::/0                silent-discard, dsn


Would it be possible to allow "outgoing" DSN only for my 
(sasl-authenticated) users?


Cheers,

Marek
