52For most gentoo users, a simple mail client and fetchmail will do. However, if
53you're hosting a domain with your system, you'll need a full blown MTA (Mail
54Transfer Agent). And if you're hosting multiple domains, then you'll definitely
55need something more robust to handle all of the email for your users. This
56system was designed to be an elegant solution to that problem.
57</p>
58
59<p>
60A virtual mail system needs to be able to handle email for numerous domains
61with multiple users over a variety of interfaces. This presents some issues
62that must be dealt with. For instance, what if you have two users on different
63domains that want the same user name? If you are providing imap access and
64smtp-auth, how do combine the various authentication daemons into a single
65system? How do you provide security for the numerous components that comprise
66the system? How do you manage it all?
67</p>
68
69<p>
70This howto will show you how to set up with a mail system capable of handling
71mail for as many domains as your hardware can handle, supports virtual mail
72users that don't require shell accounts, has domain specific user names, can
73authenticate web, imap, smtp, and pop3 clients against a single database,
74utilizes ssl for transport layer security, has a web interface, can handle
75mailing lists for any domain on the machine, and is controlled by a nice,
76central and easy mysql database.
77</p>
78
79<p>
80There are quite a variety of ways to go about setting up a virtual mailhosting
81system. With so may options, another may be the best choice for your specific
82needs. Consider investigating <uri>http://www.qmail.org/</uri> and
83<uri>http://www.exim.org/</uri> to explore your options.
84</p>
85
86<p>
87The following packages are used in this setup: apache, courier-imap, pam_mysql,
88postfix, mod_php, phpmyadmin, squirrelmail, cyrus-sasl, mysql, php, and
89mailman.
90</p>
91
92<p>
93Make sure to turn on the following USE variables in <path>/etc/make.conf</path>
94before compiling the packages: <c>USE="mysql pam-mysql imap libwww maildir
95sasl ssl"</c>. Otherwise you will most likely have to recompile things to
96get the support you need for all the protocols. Further, it's a good idea to
97turn off any other mail and network variables, like ipv6.
98</p>
99
100<impo>
101This howto was written for postfix-2.0.x. If you are using postfix &lt; 2 some
102of the variables in this document will be different. It is recommended that you
103upgrade. Some other packages included in this howto are version sensitive as
104well. You are advised to read the documentation included with packages if you
105run into issues with this.
106</impo>
107
108<impo>
109This document uses apache-1.3.x. Apache-2 has been marked stable in portage.
110However there are still a number of issues with php integration. Until php
111support in apache-2.0.x is marked stable, this guide will continue to use the
1121.3.x version.
113</impo>
114
115<impo>
116You need a domain name to run a public mail server, or at least an MX record
117for a domain. Ideally you would have control of at least two domains to take
118advantage of your new virtual domain functionality.
119</impo>
120
121<impo>
122Make sure <path>/etc/hostname</path> is set to the right hostname for your mail
123server. Verify your hostname is set correctly with <c>hostname</c>. Also
124verify that there are no conflicting entries in <path>/etc/hosts</path>.
125</impo>
126
127<note>
128It is recommended that you read this entire document and familiarize yourself
129with all the steps before attempting the install. If you run into problems with
130any of the steps, check the troubleshooting guide at the end of this document.
131Also, not all the referenced packages are necessary, this set up is very
132flexible. For instance, if you do not desire a web interface, feel free to skip
133the squirrelmail section.

155After postfix is installed, it's time to configure it. Change the following

421Verify that the above AUTH and STARTTLS lines now appear in your postfix
422install. As I said before, as it stands now AUTH will not work. that's because
423sasl will try to auth against it's sasldb, instead of the shadow file for some
424unknown reason, which we have not set up. So we're going to just plow through
425and set up mysql to hold all of our auth and virtual domain information.

351<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> 594

898One further note, current versions of mailman install to /usr/local/mailman. If
899you're like me and wish to change the default install location, it can be
900overridden in the ebuild filoe by changing the INSTALLDIR variable.

657<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> 1050

672<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> 1084

694<p>Repeat after me, logs are my friend. My next troubleshooting stop is always the logs.

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> 1124
