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?
Best regards,
Renne
