Come creare un infrastruttura PKI con OpenSSL

Recentemente ho realizzato un How To su come sfruttare il programma OpenSSL per realizzare un'infrastruttura PKI (Public Key Infrastructure) con cui generare i certificati digitali per poter consentire ad una persona di firmare e criptare digitalmente i propri messaggi email, accedere in modo sicuro (via SSL) alla propria casella di posta elettronica ed alla Webmail (utilizzando Postfix, Courier e SquirrelMail)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)

This document describes how to install a Postfix mail server based that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

The Perfect Server - Fedora 9

This is a detailed description about how to set up a Fedora 9 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable) with PHP5 and Ruby, Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Fedora 9, but should apply to the 64-bit version with very little modifications as well.

Virtual Users And Domains With Postfix, Courier And MySQL (Mandriva 2008.0)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.
