Amahi Mail System

	WARNING
	This should only be attempted by advanced users. It is still under development.

DISCLAIMER: This is for Fedora 14 ONLY! Although tested, use at your own risk. I cannot guarantee that it will work for your system or not cause any serious problems.

Purpose

The primary intent of the Amahi Mail System is to allow you to use your Home Digital Assistant (HDA) as a mail server.

• It allows you to send/receive mail from your HDA. There are some quirks depending on if you have a registered domain with a paid service provider (i.e. GoDaddy, Host Gator). With these services, there is typically what is called a MX record associated with the domain name. This will allow you to send/receive mail as your hostname (i.e. myhda@home.com).

• If you use the free ones (i.e. user.yourhda.com, no-ip.org), you will have to masquerade your email address as your ISP (i.e. myhda@yourisp.com). This will ensure you can receive email replies from those you send from your HDA.

How to Install/Uninstall (Automated)

• Special access must be requested to install Amahi Mail System.
• Once granted, install/uninstall via the Applications tab in the Amahi Dashboard.

How to Install (Manual)

Here's the sequence of events to get the virtual email server up and running:

1. Restart your HDA so it's fresh for the install. This is not required, just a recommendation.
2. Enable Advanced Settings in the Amahi Dashboard (Settings-->Settings)
3. Create a web app in Amahi named ams.
4. Open a terminal window, become root, and navigate to /var/hda/web-apps/ams directory.
5. Download mail-server-1.8.8.tar.gz (sha1sum 950bd51ecedf1c86d12c4830320f458502917a12) to this directory and extract it into html directory of ams (archive content).
6. Ensure you recursively change ownership of the files to apache:users.
7. Need to make a directory called elevated in ams. Copy mail-setup.sh and del-maildir.sh to that location.
8. Ensure mail-setup.sh and del-maildir.sh are executable.
9. Create the database and insert the data from the mail.sql file located in the config directory.
10. Navigate to http://ams in your favorite web browser and you should see the login page.
11. Enter credentials (admin/amahi) and choose Login to display the install page (See Tips for how to change the login info).
12. Complete all the required info. Once finished, select the click the NEXT button and the data will be added to the database.
13. Next, a screen will appear with a INSTALL button, click it to begin. You will also notice a log link so you can monitor the install.
14. Use your favorite mail client, Roundcube, AtMail, or SquirrelMail to access your new mail account.
15. Use the built-in tool to manage Virtual User information in the database. DadaBIK, phpMyAdmin, or Adminer can also be utilized.

Example Install Terminal Session

bash code
​su - cd /var/hda/web-apps/ams wget http://dl.getdropbox.com/u/1380867/mail-server-1.8.8.tar.gz mkdir elevated cd html tar -xzpf ../mail-server-1.8.8.tar.gz cp mail-setup.sh ../elevated cp del-maildir.sh ../elevated chmod 755 ../elevated/mail-setup.sh ../elevated/del-maildir.sh chown -R apache:users ../html ../elevated hda-create-db-and-user mail mysql -umail -pmail mail < config/mail.sql​

How to Uninstall (Manual)

To uninstall, do the following:

1. Open a terminal window, become root, and navigate to /var/hda/web-apps/ams/html directory.
2. Remove the database.
3. Ensure mail-remove.sh is executable.
4. From the html directory, run the script. This may take a while to complete.
5. Close the terminal window and remove the web app in Amahi named ams.

Example Uninstall Terminal Session

bash code
​su - cd /var/hda/web-apps/ams/html chmod 755 mail-remove.sh hda-create-db-and-user -d mail ./mail-remove.sh​

Tips

• To permanently change your hostname from localhost.localdomain, see this article.
• Should your mail server hang up and stop working, you can most likely fix it with the following two scripts. Place them in /var/hda/web-apps/ams/elevated directory. You must run these as root user :

start.sh (execute stop.sh first):

Text
​/etc/init.d/courier-authlib start; /etc/init.d/sendmail stop; /etc/init.d/postfix start; /etc/init.d/saslauthd start; /etc/init.d/courier-authlib restart; /etc/init.d/courier-imap start; /usr/bin/freshclam; /etc/init.d/amavisd start; /etc/init.d/clamd.amavisd start; /etc/init.d/postfix start; spamassassin --lint; /etc/init.d/amavisd restart; sa-update --no-gpg;​

stop.sh (run prior to start.sh):

Text
​/etc/init.d/courier-authlib stop; /etc/init.d/sendmail stop; /etc/init.d/postfix stop; /etc/init.d/saslauthd stop; /etc/init.d/courier-imap stop; /etc/init.d/amavisd stop; /etc/init.d/clamd.amavisd stop; rm -f /var/spool/amavisd/clamd.sock;​

Ensure you set the permissions on both files:

bash code
​chown apache:users start.sh stop.sh chmod 755 start.sh stop.sh​

• You can change the Login Credentials for the integrated database manager/web-based installer by doing the following:
  1. Open the Login-class.php file in the /var/hda/web-apps/ams/html directory
  2. On lines 29 and 32, change to whatever works for you
  3. Save and now you can log in using the new credentials
• Add NEW users to the foo.com domain (does not include any DNS MX records). Modify the mail database and substitute your information accordingly:
  1. In the users table, insert a new record with the following information...
     • user: user@foo.com
     • password: choose 'ENCRYPT' for the function and enter the users password. (Alternatively, you can have the user enter their password)
     • quota: do NOT edit this field (unless you know what you are doing)
  2. In the forwardings table, insert a new record for each forwarded email addresses to user@foo.com
  3. Run the command line below to set up the /home/vmail/foo.com/user mail files:

bash code
​mailx -s Welcome user@foo.com < /var/hda/web-apps/ams/html/config/welcome.txt​

• Add an additional mail domain (does not include any DNS MX records). Modify the mail database and substitute your information accordingly:
  1. Scenario - Creating a mail domain e.g. :
     • domain is: bar.com
     • server is: foo.bar.com
     • admin user is: me@bar.com
  2. In the mail mySQL database tables:
     • domain: add bar.com
     • transport: add bar.com
     • user: add me@bar.com
     • forward: add postmaster@bar.com, and abuse@bar.com to me@bar.com
  3. Run the command line below to set up the /home/vmail/bar.com/me mail files:

bash code
​mailx -s Welcome me@bar.com < /var/hda/web-apps/ams/html/config/welcome.txt​

• For every domain supported, the following either need to be added as users or forwarded. Without them a site MAY end up on various spam block lists:

Text
​postmaster@foo.com abuse@foo.com​

Conclusion

You should now be able to log in to your account. There will be 2 messages, one is a welcome and the other is a SPAM test to show it's working. Direct any questions or comments to <support [at] amahi [dot] org>.
