Ah the age old distro argument. Thankfully this set up should work on most distros. I used to base this howto on Mandrakenow Mandriva. I started this new edition on a Gentoo box. But I dont have the patience for Gentoo. Mandriva Power editions. Why Ubuntu Its free, simple and slick. As Ubuntu is derived from debian the installations. Please refer to my other editions for details on RPM. MTA Postfix. Simple, free and slick. Yup I am a sucker for anything that works easily. Postfix is powerful, well established. PopIMAP Courier IMAP or Dovecot. My first mail server installation was with Courier. I have not found a reason to change this as again. A popular alternative, is Dovecot. Database My. SQL. Although I use Firebird for my application development. HibernateC JDBC hybrids. My. SQL is well supported for the sort of lookups required. Content Check Amavisd new. Easy plug in solution for spam, virus checking etc. Anti Spam Spam. Assassin. Powerful renowned spam fighting tool. Anti Virus Clam. AV. Free virus scanner that can be trusted and includes update daemon. Authentication Cyrus SASL. Secure and trusted cryptography technology. SMTP traffic. Postgrey is an excellent little script to stop 9. All it does is on first contact for specific from to combinations. When proper servers try again after a few minutes it lets it through.

Formerly referenced as SSL. Web. Mail Squirrel. Mail or Roundcube. Easy to set up php based web mail client. Extensive plugin selection. Ajaxified prettier web mail client. Not quite as solid as Squirrel. Mail. Platform Amazon ec. This guide can be installed locally, co located or in the cloud. My preference is ec. I provide ec. 2 based examples. Please see software links appendix for further information. In that section there is more links to. Further software and tweaks are discussed in the. Also review other peoples opinion on these packages via my references. Installation. Distribution. This section is different for every distribution and for every version. This howto is based on Ubuntu and its base of debian which uses apt get. Therefore this section uses apt packages to its fullest. For other installation method please refer to previous editions. My 2nd editionoutdated has instructions. Mandriva, general RPM and tarball compiling. To follow the rest of this howto with another distribution. E. g My. SQL lookup on postfix and sasl, php in apache etc. I have set up mail servers using the 3. E. g. Mac platforms should work too. With installing Ubuntu you have a choice of which base system to install. You may choose server or desktop image or very basic setups. I will assume a server install, but it should not differ. If you have chosen an ec. I strongly suggest choosing the latest LTS version of Ubuntu, not the versions in between. Once this is set up you will tinker very little with it, and it will quickly be annoying to upgrade distributions once a year. Ps. Please note that after a while Ill stop specifying the use of sudo. My advice is to use sudo. For assistance with repositories, refer to this article on ubuntus wiki. I would recommend find a repository archive close to your servers location. For example a country specific one or if hosted on AWS EC2 an archive in your AWS region. Remember these are highly security sensitive so choose one you trust. You need the main and universe repositories. The multiverse, restricted and partner can be added but are not needed. Do not add backports. Uncomment the lines that have commented out universe. E. g. here are mine for ec. Europe. deb http eu west 1. Note the security repository always have to go to the non mirrored server. As mentioned in the previous edition. You need to install a whole bunch of packages. We will install them bit by bit. But first check your package sources are correctly pointing to main multiverse restricted universe. Ubuntu version. sudo vi etcaptsources. Secondly update your current system. Note aptitude is no longer supplied in the base install of Ubuntu. This is due to some concurrency issues. Some part of this document may still refer to aptitude. You should use the original apt get instead. Additional packages. I also install a few other packages that I personally prefer. But nothing todo with the mail server. Mutt is a very usefull command line mail client that I always install. I usually do that at the end when testing so that it doesnt. Postfix before I am ready. Package status. To find out which packages you may have installed. And to find which are available. Configuration. Simple mail server. Now lets configure a simple mail server using some of. Firewall. Shorewall. Not essential for an EC2 image. It is essential for a normal server. UFW is bundled with recent Ubuntu distributions. I still prefer Shorewall for servers. Installationsudo apt get install shorewall shorewall doc. Amazon provides a firewall access control for its servers. And in all others situations a must have.
