Re: Postfix 2.8.x anti anti backscattering settings

   Ohh. So there is only one solution - on mail server generate an
alias list that contains aliases and result. Like :

chose OK
user OK
...
...

   And in main.cf use directive
smtpd_recipient_restrictions = <other options>,check_recipient_access
hash:/etc/postfix/alias_list,<other options>

   So we'll generate aliases into a "alias_list" file and scp it from
email server to incomming smtp and use it in postfix.

   Is it only one option ? Or there are better ? Just asking.

   Thanks very much.
