Exim4 Exim4 is a Message Transfer Agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the internet. Exim4 can be installed in place of sendmail or Postfix, although the configuration of Exim4 is quite different to that of sendmail. Install the exim4 package from the Main repository using your favorite package manager (see InstallingSoftware). To configure Exim4, run the following command: sudo dpkg-reconfigure exim4-config The user interface will be displayed. All the parameters you configure in the user interface are stored in /etc/exim4/update-exim4.conf.conf file. sudo update-exim4.conf The master configuration file will be generated and stored in /var/lib/exim4/config.autogenerated. Note: Never directly edit the master configuration file, /var/lib/exim4/config.autogenerated. The following command will start the exim4 daemon: sudo /etc/init.d/exim4 start TODO: This section should cover configuring SMTP AUTH with exim4. SMTP Authentication MAIN_TLS_ENABLE = yes

Ubuntu Lucid Lynx (Ubuntu 10.04) [ISPConfig 2] - Page 5 15 Postfix With SMTP-AUTH And TLS In order to install Postfix with SMTP-AUTH and TLS do the following steps: aptitude install postfix libsasl2-2 sasl2-bin libsasl2-modules procmail You will be asked two questions. Answer as follows: General type of mail configuration: <-- Internet Site System mail name: <-- server1.example.com Then run dpkg-reconfigure postfix Again, you'll be asked some questions: General type of mail configuration: <-- Internet Site System mail name: <-- server1.example.com Root and postmaster mail recipient: <-- [blank] Other destinations to accept mail for (blank for none): <-- server1.example.com, localhost.example.com, localhost.localdomain, localhost Force synchronous updates on mail queue? Next, do this: Afterwards we create the certificates for TLS: mkdir /etc/postfix/ssl cd /etc/postfix/ssl/ openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024 chmod 600 smtpd.key openssl req -new -key smtpd.key -out smtpd.csr openssl rsa -in smtpd.key -out smtpd.key.unencrypted and
Configuring Sendmail with smarthost Ubuntu Gutsy - Scalix Wiki Important Note Please note that these manual installation instructions should only be used on Ubuntu distributions, such as Ubuntu Gutsy Gibbon 7.10 server, the distribution the document was written for. If you install Scalix on an unsupported platform, this invalidates your ability to receive Scalix support. This document might be inaccurate and under construction. As Ubuntu 7.10 is an unsupported platform there is currently no manual describing the configuration of sendmail (the recommended MTA to be used with Scalix) to be used with a smarthost (smtp relay). So below you'll find a how-to that describes the configuration of sendmail to be used with Scalix on a Ubuntu 7.10 server. Sendmail is a remarkably flexible program, supporting many kinds of mail transfer and delivery including the SMTP, which Scalix uses. A smart host is a type of mail relay server which allows an SMTP server to route e-mail to an intermediate mail server rather than directly to the recipient’s server. Where:
Certificates One of the most common forms of cryptography today is public-key cryptography. Public-key cryptography utilizes a public key and a private key. The system works by encrypting information using the public key. The information can then only be decrypted using the private key. A common use for public-key cryptography is encrypting application traffic using a Secure Socket Layer (SSL) or Transport Layer Security (TLS) connection. A Certificate is a method used to distribute a public key and other information about a server and the organization who is responsible for it. To set up a secure server using public-key cryptography, in most cases, you send your certificate request (including your public key), proof of your company's identity, and payment to a CA. Continuing the HTTPS example, a CA-signed certificate provides two important capabilities that a self-signed certificate does not: The process of getting a certificate from a CA is fairly easy. openssl genrsa -des3 -out server.key 1024
Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3) - Page 5 16 Install PureFTPd And Quota PureFTPd and quota can be installed with the following command: apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool Edit the file /etc/default/pure-ftpd-common... vi /etc/default/pure-ftpd-common ... and make sure that the start mode is set to standalone and set VIRTUALCHROOT=true: Now we configure PureFTPd to allow FTP and TLS sessions. If you want to allow FTP and TLS sessions, run echo 1 > /etc/pure-ftpd/conf/TLS In order to use TLS, we must create an SSL certificate. mkdir -p /etc/ssl/private/ Afterwards, we can generate the SSL certificate as follows: openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem Country Name (2 letter code) [AU]: <-- Enter your Country Name (e.g., "DE"). Change the permissions of the SSL certificate: chmod 600 /etc/ssl/private/pure-ftpd.pem Then restart PureFTPd: /etc/init.d/pure-ftpd-mysql restart Edit /etc/fstab. vi /etc/fstab mount -o remount /
Postfix Postfix is the default Mail Transfer Agent (MTA) in Ubuntu. It attempts to be fast and easy to administer and secure. It is compatible with the MTA sendmail. This section explains how to install and configure postfix. It also explains how to set it up as an SMTP server using a secure connection (for sending emails securely). To install postfix run the following command: sudo apt-get install postfix Simply press return when the installation process asks questions, the configuration will be done in greater detail in the next stage. To configure postfix, run the following command: sudo dpkg-reconfigure postfix The user interface will be displayed. Internet Site mail.example.com steve mail.example.com, localhost.localdomain, localhost No 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/24 0 + all Now is a good time to decide which mailbox format you want to use. To configure the mailbox format for Maildir: sudo postconf -e 'home_mailbox = Maildir/' mechanisms = plain login
