43<p>For most gentoo users, a simple mail client and fetchmail will do. However, if you're hosting a domain with your system, you'll need a full blown MTA (Mail Transfer Agent). And if you're hosting multiple domains, then you'll definitely need something more robust to handle all of the email for your users. This system was designed to be an elegant solution to that problem.</p> 53
44<p>A virtual mail system needs to be able to handle email for numerous domains with multiple users over a variety of interfaces. This presents some issues that must be dealt with. For instance, what if you have two users on different domains that want the same user name? If you are providing imap access and smtp-auth, how do combine the various authentication daemons into a single system? How do you provide security for the numerous components that comprise the system? How do you manage it all?</p> 54<p>
45<p>This howto will show you how to set up with a mail system capable of handling mail for as many domains as your hardware can handle, supports virtual mail users that don't require shell accounts, has domain specific user names, can authenticate web, imap, smtp, and pop3 clients against a single database, utilizes ssl for transport layer security, has a web interface, can handle mailing lists for any domain on the machine, and is controlled by a nice, central and easy mysql database. </p> 55For most Gentoo users, a simple mail client and fetchmail will do.

83There are quite a variety of ways to go about setting up a virtual mailhosting
84system. With so may options, another may be the best choice for your specific
85needs. Consider investigating <uri>http://www.qmail.org/</uri> and
86<uri>http://www.exim.org/</uri> to explore your options.
87</p>

90The following packages are used in this setup: apache, courier-imap, courier-authlib
91postfix, mod_php, phpmyadmin, squirrelmail, cyrus-sasl, mysql, php, and
92mailman.
93</p>
94
95<p>
96Make sure to turn on the following USE variables in <path>/etc/make.conf</path>
97before compiling the packages: <c>USE="mysql imap libwww maildir

99get the support you need for all the protocols. Further, it's a good idea to
100turn off any other mail and network variables, like ipv6.

104This howto was written for postfix-2.0.x. If you are using postfix &lt; 2 some
105of the variables in this document will be different. It is recommended that you
106upgrade. Some other packages included in this howto are version sensitive as

108run into issues with this.

112This document uses apache-1.3.x. Apache-2 has been marked stable in portage.
113However there are still a number of issues with php integration. Until php
114support in apache-2.0.x is marked stable, this guide will continue to use the
1151.3.x version.

119You need a domain name to run a public mail server, or at least an MX record
120for a domain. Ideally you would have control of at least two domains to take
121advantage of your new virtual domain functionality.
122</impo>
123
124<impo>
125Make sure <path>/etc/conf.d/hostname</path> is set to the right hostname for
126your mail server. You can apply any changes you make to this file by running
127<c>/etc/init.d/hostname restart</c>. Verify your hostname is set correctly with
128<c>hostname</c>. Also verify that there are no conflicting entries in
129<path>/etc/hosts</path>.

133It is recommended that you read this entire document and familiarize yourself
134with all the steps before attempting the install. If you run into problems with
135any of the steps, check the troubleshooting guide at the end of this document.
136Also, not all the referenced packages are necessary, this set up is very
137flexible. For instance, if you do not desire a web interface, feel free to skip

376<p>Now enter the phpmyadmin page and browse the tables. You'll want to add in your local aliases, edit your user table to add a test user, and change your transport table to add information about your domains. The default values supplied with the dumpfile should be a sufficient guide to what values need to go where. Make sure that if you put information in the database that it is accurate. For instance, make sure the local users home dir exists and that the correct uid/gid values are in place. The maildirs should be created automatically by postfix when the user receives their first email. So, in general, it's a good idea to send a &quot;Welcome&quot; mail to a new user after you setup their account to make sure the .maildir gets created. </p> 607

712<p>Troubleshooting: This is a short troubleshooting guide for the set up we've detailed how to install here. It is not exhaustive, but meant as a place to get you started in figuring out problems. With a complicated setup such as this, it's imperative that you narrow down the problem to the particular component that is malfunctioning. In general I do that by following a few steps. Start from the base of the system and work your way up, ruling out components that work along the way until you discover which component is having the problem.</p> 1028

You can debug all you want, but if you're not passing the right information back and forth to your mail system, it's not going to work. If you make a change to a config file for a service, make sure you restart that service so that the config change gets picked up.</p> 1044

727<p>If it's not running, start it up. It's awful hard to debug a service that isn't running. Sometimes a service will act like it's started but still not function. Sometimes, when a bad config is used, or a bad transmission comes into a mail component, the service will hang and keep the port from being used by another process. Sometimes you can detect this with netstat. Or, if you've been at it awhile, just take a break and reboot your box in the meantime. That will clear out any hung services. Then you can come back fresh and try it again.</p> 1062

749<p>Repeat after me, logs are my friend. My next troubleshooting stop is always the logs. Sometimes it's helpful to try a failed operation again then check the logs so that the error message is right at the bottom (or top depending on your logger) instead of buried in there somewhere. See if there is any information in your log that can help you diagnose the problem, or at the very least, figure out which component is having the problem.</p> 1102
