I want to add following to my postfix configuration :
smtpd_restriction_classes = allowed_only
allowed_only = check_sender_access hash:/etc/postfix/,postfix_allow_dl, reject
For smtpd_recipient_restrictions, I can make enteries in /opt/zimbra/conf/postfix_recipient_restrictions.cf
but for smtpd_restriction_classes, i don't know where to make enteries.
Also, I need to make two lists postfix_list_dl, postfix_allow_dl.
What is the appropriate place where these lists can reside ?
Is there a wiki / help for such things ?
