Configure Postfix, PostfixAdmin, Dovecot & SMTP-Auth SASL Using MySQL on Ubuntu 12.04 LTS

Setting Up Postfixadmin

Postfixadmin provides a web interface to set up virtual domains, mailboxes and provides delegated admin.  All the MySQL tables, configuration of Postfix and Dovecot allows Postfixadmin to work with little or no configuration.

[This needs work]

Download the debian package for postfixadmin the one found at this point in time is postfixadmin_2.3.5-1_all.deb . To install issue the following command :

dpkg -i postfixadmin_2.3.5-1_all.deb

[I ran into problems here will need to do this again to understand how I resolved this]

To configure postfix admin, you will need to go to the following url on your local mail server : http://[ipaddess]/postfixadmin/setup.php .  This will run a setup and inform you of anything that needs attention.  At the bottom of this page it will show the following :

Choose a complex password, and click generate password which should be used to set subsequent .  This will generate a password hash line as follows that should be placed into the /etc/postfixadmin/config.inc.php file as follows :

// In order to setup Postfixadmin, you MUST specify a hashed password here.
// To create the hash, visit setup.php in a browser and type a password into the field,
// on submission it will be echoed out to you as a hashed value.
$CONF['setup_password'] = '13a83641cc7369c6bb385b8c0897bb71:2fb691385c74438dc4475f37096bde9388ec561a';

Back to the browser and the following will be shown :

As shown above a SuperAdmin account is needed to proceed, enter the setup password you generated earlier, this is the one that was placed into the config.inc.php file.  This will allow you to generate an Admin id, choose something that is of the email address found in the System Email domain e.g. your.name@myhosting.co.uk.  Once this has been done logon with this superadmin account and setup the relevant email boxes, and virtual domains.

Looking into the /etc/postfixadmin/config.inc.php are a host of other options including quotas etc.

This concludes the configuration for postfixadmin.  You should have a system that allows users to pop3, or imap their email, allow them to send emails via SMTP and StartTLS using there pop3 or imap credentials.

  1. AAAaarrgh, SOOOooo close 🙂
    This whole setup was going along absolutely Bang On. Just systematic clockwork, then couldn’t connect at the testing phase.
    Great Post though. I’m really surprised no one else has posted on this tut. as it is the perfect setup in my mind.

    Question for the owner… Could you put the versions of the packages you’re using up for us? I’ll still have to work out how to install them on my system, but that would be a great help. Dovecot upgrades are proving a real hassle to a lot of us. Specially without updated tuts.

    Again, great post, hope to hear about those package versions too.

    Thanx

  3. You have a bug in your postconf section:

    This line breaks the authentication with an error about the mailbox. “sudo postconf -e ‘virtual_mailbox_maps = /etc/postfix/mysql_virtual_mailbox_maps.cf'”

    Update it to include the proxy:mysql and it works.

    sudo postconf -e ‘virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf’

    Great document.

  4. I found this guide when trying to set up my own mail server. There are a few errors in it, however, and I’m only discovering them through encountering issues in my set up – so although I’ve noticed a couple there are maybe others.

    The first thing I’d say to people reading this is that you will need to use sudo a lot or else log in as root. If you mentioned that I didn’t notice it. When copying and pasting it is handy if you have a document ready with your usernames, passwords and the word sudo in there so you can copy/paste from this guide to a doc to your terminal.

    Next there is an issue with the line

    postconf -e ‘virtual_mailbox_maps = /etc/postfix/mysql_virtual_mailbox_maps.cf’

    which should be

    postconf -e ‘virtual_mailbox_maps = hash:/etc/postfix/mysql_virtual_mailbox_maps.cf’

    note the word “hash” above.

    Secondly you create the document
    etc/postfix/mysql_virtual_domains_map.cf

    when you should create
    mysql_virtual_domains_maps.cf

    Note the ‘s’, maps. Alternatively you should link to ‘map’ instead of ‘maps’ later in the guide.

    There may be others, it’s more than likely that I’ll not come back to update this post if I find more so beware, however, this guide can carry you most of the way.

    Sometimes when I am setting up a server or something I’ll take notes and think to myself that I will write a blog post about it some time. Then I come across an error, spend half the day fixing it and when I get around to writing the blog article I realise that having not taken proper notes when fixing the error my guide becomes useless to others. This is the sort of thing that’s happened here, you can tell by the way you wrote out the last page and how you start trying to debug your dovecot when it’s quite likely it was actually a postfix error that was catching you out.

  5. Thank you to all for taking time to point out any errors, I have double checked my own configuration and have found the line should read:

    postconf -e ‘virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf’

    I not sure it should read with a hash: prefix, as its not a hash file, but contains the SQL to query the virtual mailboxes.

    Where it states create a file :/etc/postfix/mysql_virtual_domains_map.cf this was a typo, I have now corrected this in the article, sorry if it caused any confusion, but the article should be now correct.

    This can be a challenge setting this up, but I am really keen that if people run into problems that they leave comments so that I change and improve this article for everyone.
