The memory usage is caused by smtpd_recipient_restrictions = check_client_access cidr:/etc/postfix/dnswl/postfix-dnswl-header, check_client_access cidr:/etc/postfix/dnswl/postfix-dnswl-permit, This are whitelists downloaded from DNSWL every night. Each file is about 4 MBytes and bloats EACH smtpd-process by 10 MBytes. Is there any reason why such lists are not in shared memory? Is it normal that TLS bloats each smtpd-process by about 1 Mbyte?
