Hi all, I'm trying to add more security to my email service, so searching on the web i found this: http://www.backscatterer.org/?target=usage i think is useful for me, so i implement the postfix safe mode, but when i run it i get the following error: Code: postfix/smtpd[5323]: error: unsupported dictionary type: dbm Checking i run "postconf -m" command and turns out that my linux does not support DBM databases, i've been trying to install the support for that without success, so if anyone can tell me how or share a link i will appreciate. Im using Debian 9
